The Complete Incomplete Guide to Blisters

By: Will Babb

If you’ve ever done a fair amount of hiking, then you’ve experienced a hiker’s worst nightmare- blisters or hot spots. And if you haven’t, then you’re either lying about that or you haven’t hiked enough. The problem with that is that despite being such a common problem, they can be prevented pretty easily with the right gear. And despite being such a small and preventable  problem, they can wreak havoc on your hike. A few small blisters can quickly turn a long hike sour and leave you limping to the trailhead or in tears on the side of the trail. If you meet ten different people on the trail and ask them how to treat blisters, chances are you’ll hear about ten different answers. So because blisters are both simple and confusing, I’m here to give you a complete incomplete guide to blisters- their causes and how to prevent them as well as what to do when you get them so that you can hike pain free and fully enjoy all that the outdoors have to offer.

Causes and Prevention

In almost every situation blisters are caused by excessive friction or rubbing on your foot. A hot spot is the start of a blister- when you first begin to feel a burning sensation from the friction, and if left untreated will turn into a blister. The source of this friction is not always easy to diagnose as there are a variety of causes. Often an improperly fitting shoe can be the cause of blisters- both shoes that are too big or too small can cause hot spots and blisters. If the shoes are too big, your heel will slide out the back as you walk and generate a blister on the back of your foot, or even your toes sliding too much will cause blisters. If the shoes are too small, your toes will hit the front of the shoe, especially on steep descents, and can lead to blisters. And if the shoes are too tight on the sides, they can cause your toes to rub against each other and cause blisters between your toes. Your shoes are the most important piece of gear you own, so choosing a quality shoe that fits properly is vital. It is also important to remember that your feet swell a little throughout the day and as you hike so it is often best to leave a little bit of extra space in the shoes to accommodate this as long as the heel doesn’t slip out the back.

Once you get a shoe that fits correctly, choosing the right sock is the next task. Luckily, socks are usually easier to choose than shoes. Again, socks that are too big will cause rubbing or bunching and eventually blisters. For anything from day hikes to long term backpacking trips, merino wool is generally the best way to go with socks. Brands such as Smartwool, Point 6, and Darn Tough all use high quality merino wool in their socks. Merino is superior to cotton for several reasons- it dries quickly, insulates well in winter, wicks moisture in summer to keep you cool, and does not smell as quickly as cotton will. These benefits become essential in preventing blisters. Wet socks are not only uncomfortable but can also, you guessed it, lead to blisters. A quick drying merino wool sock that breathes well so you sweat less will do a much better job preventing blisters than your average cotton sock. I prefer a lightweight merino sock in the summer such as the micro cushion and something a littler warmer and thicker in the colder months. Some people prefer a thin liner sock as an extra layer of protection, but beware because sometimes this extra layer can lead to increased friction. If you have problems with blisters developing between your toes, I find that wearing a toe sock, such as something from Injinji, is a great way to prevent that problem.

The right socks and shoes won’t leave you blister free, but they go a long ways towards reaching that goal. If you do enough hiking, you’ll inevitably get stuck in a rainstorm and hike in wet shoes and socks for a few miles. I find that hiking anything more than a few miles in wet footwear is a sure cause of blisters. I always like to bring along a third pair of socks on backpacking trips for this reason. Sure, I can save on pack weight and get by with only two, but if I get a few days of rain that third pair can mean the difference between dry, happy feet or swollen, red, blistered feet. Other than packing extra socks, there’s no sure way to avoid blisters in this situation, but there’s a few steps you can take to try to hold them off as long as possible. Taking frequent breaks when hiking, and being sure to pull off your shoes and socks when you do, can help you dry out quicker and give your feet a break. If your feet get wrinkled in wet socks like they do in a swimming pool it’s time to take a break and air out your feet, which will be tender and subjective to blisters. Along this same line, bringing along a pair of camp shoes that you can wear without socks at the end of the day will let your feet get additional ventilation and give your hiking shoes a chance to dry out.

Treatment

Once you determine the cause of a blister, it becomes possible to treat it. If you do some research on blisters, you’ll find that some sources recommend popping blisters in every situation, some recommend leaving them be, and others recommend draining the fluid on a case by case basis. Not popping a blister reduces the chance of infection, so this is often a great way to go if you’re in the backcountry and my personal recommendation. If you choose to go this way, protecting the hot spot or blister so it doesn’t get worse should be your next step and then you can hike relatively pain free. Depending on the location of your blister, sometimes leaving it unpopped will be too painful. If this is the case, you can pop the blister, but be sure to drain it of any excess fluid and clean it well to remove any bacteria using an antiseptic or, if unavailable, clean water. After cleaning it, it is essential to protect it and keep it clean so that the friction stops and infection is prevented. And if you’re uncomfortable with popping a blister, it’s always okay to leave it as is and simply cushion it well until you can get out of the woods and properly care for it- always use whichever treatment method is comfortable for you.

Below are several common products out there that are often used for blister treatment. Over the course of several years spent hiking and backpacking at Philmont Scout Ranch, local trails, and 2,200 miles on the Appalachian Trail I’ve tested out most of these products and figured out which ones I can come to rely on time and time again.

I have found that the absolute best method for both prevention and treatment of blisters is Nexcare absolutely waterproof tape. It is a stretchy, soft tape that can easily be found in almost any store. Unlike almost any of the other treatment methods here, this one works great in early and late stages and can keep you on the trail longer. This was my go to treatment method this past year on the Appalachian Trail. If I felt a hot spot coming on, a few strips of tape would eliminate the problem. If I did get blisters, a folded up piece of toilet paper or a piece of moleskin beneath the tape would protect the blister so it could heal. The tape stayed on even when wet and didn’t fall off after 20 and 25 mile days, although it was still easy to peel the tape off at the end of the night and didn’t leave any sticky residue, as duct tape or gel pads will. Although not specifically meant for blister treatment like moleskin or specialized gel pads, this method worked way better for me than any of those listed below and can be used for a variety of other backcountry uses, even just holding a band-aid on either on or off the trail.

The most common method of treating a blister is moleskin, which can be effective it is used properly. It works great in situations when the shoe or sock is rubbing too much because it protects the blister or hot spot well. On the downside, I find that it doesn’t stick to skin very well, especially as you continue to hike, but that can easily be solved with a few strips of tape. To use moleskin, simply cut off a small square of moleskin and cut a hole in the middle where the blister is and apply it. The moleskin is great because it doesn’t cover up the blister itself and allows it to breathe while still eliminating the friction around the area. Moleskin works best when you can get it on early, as a hot spot is forming, even before the blister has formed.

Another option is a gel pad or a “second skin” treatment. They work great at preventing hot spots from becoming blisters and I’ve also used them on blisters that have been popped with decent results, although they won’t keep your blister clean or allow it to heal properly, so they are only great in this situation for short intervals to alleviate pain as you finish a hike. My problem with the gel pads is that they can actually be too sticky and difficult to remove and leave a residue on your skin and socks. I prefer not too spend the additional money on a specialized product such as this when I can use some gauze and waterproof tape to fix the same problem.

Many marathon runners swear on using Vaseline on their feet to prevent blisters. The Vaseline won’t eliminate rubbing, but it will eliminate the friction that builds up from the excessive rubbing. Similarly, clear nail polish works the same way. I learned from a former RRT employee and the current Wilderness First Aid instructor that applying this will create a smooth, friction-less surface on the hot spot. Both of these methods allow you to continue hiking on an existing blister or hot spot, but it isn’t universal. This method won’t work for everyone- sometimes it can actually accentuate the problem. My other problem with Vaseline is that it doesn’t allow a blister to air out, so again, it should only be used short term and won’t do anything to help the healing process.

Tape is another option for treatment, one that works best in conjunction with moleskin or a band-aid, two methods that can work well on treatment but won’t stick well on their own over time. Athletic tape and duct tape are two options- some people tape directly over a hot spot or unpopped blister but I think it’s best to tape over top of moleskin or gauze or even a piece of toilet paper. You can even apply duct tape to the inside of your boots to eliminate rough spots that might cause blisters. As sturdy as duct tape might be, I’ve found that it too is pretty much worthless if it gets wet and after long miles, even for high quality duct tape. Another tape option is Leukotape, which is a little hard to find and a little more expensive but works way better than duct tape. It will work all day, even when wet, and holds well. I don’t use it because I prefer a tape that I can easily find in stores when I need it. My problem with using tapes like these, rather than the Nexcare waterproof tape I mentioned above, is that they often leave a sticky residue on your feet and socks that can be hard to remove.

Band-aids can be extremely useful because they come in a wide variety of sizes, some small and rounded to specifically cover up blisters, but again they don’t stick well and should be used in conjunction with a quality tape.

One more piece of advice, one that probably doesn’t need said but I’m going to throw out there anyways- please don’t get a pedicure before you go hiking. Your feet won’t appreciate it and you’ll end up in a lot of pain. Save the pedicure for once you’ve returned from your trip.

I hope that you’ll find at least one of these blister treatments works for you and that you’ve learned something to make your next hike in the woods blister free and enjoyable. I tried to include as much information as I could without writing a textbook, and I think I covered all of the most popular treatments that I’m familiar with, but I’m sure I still missed a few. If there’s a home remedy or secret treatment that you think is the fountain of youth, or in this case of blister treatment, don’t hesitate to let me know- I’m always looking for more camping hacks I can take into my outdoor pursuits.

 

“The Everyday Ten Essentials”

Your Everyday Gear
Written by: Bryan Wolf

The Ten Essentials“, outdoor enthusiasts know these as the ten items that you don’t leave home without. The ten items that give you the best chance for survival in the Great Outdoors. Although lists vary, here is the gist:

 

 

1. Pocketknife
2. First Aid
3. Extra Layers
4. Rain Gear
5. Water
6. Lighting
7. Food
8. Fire Starter
9. Sun Protection
10. Map and Compass

The truth is, most outdoor adventures don’t call for an emergency fire or the use of a compass. While this list gets us through the worst nature has to throw our way it is hardly the most used equipment in the gear shed.  This list is fantastic, and I’m not disagreeing with it, at least not in this post. Rather, I wanted to create a list for our everyday challenges, for the other 5 days of the week that have us bouncing around the city from work to play before heading home to recharge the batteries and start all over again.  So what do we use everyday, that also translates to the outdoor lifestyle?

I wanted to create your “Everyday Ten Essentials“. a list that has you covered everyday, in nature, and in the office. So what items carry into both worlds? Through every season? Here is what I came up with:Everyday 10 Essentials

1. Klean Kanteen- A stainless steel drink bottle with a green footprint. Stay hydrated in any scenario and keep your favorite bottle handy. Better yet, the insulated versions are amazing and will keep hot or cold for most all of the day. Water to coffee or even taking a frozen margarita to the beach; I love this thing! (Best gift idea ever too)

2. ExOfficio Underwear- The World’s best travel and adventure underwear doesn’t have to be just that. Anti-microbial, quick dry, and well fitting comfort are features that we all deserve day in and day out. Try a pair and you may just convert your entire underwear drawer. Men’s and women’s come in several styles.

3. Wool Socks- Have you worn wool socks? Find your favorite brand; Smartwool, Darn Tough, or Point 6, and never go a day without! I was buying a new pack of cheap cotton socks every few months, they all would smell, and they all would tear. My feet feel 100x better with wool and I’ve not replaced a pair yet, plus I can take off my shoes without shame. With a variety of cushions and styles these have you covered from office to mountain peak. Did I mention they have a  lifetime warranty?!

4. Day Pack- Don’t limit yourself to a weekend pack; new Osprey, Patagonia, or Gregory packs offer lifestyle options galore.  I use my Osprey and Thule bags everyday to and from work. With a clean look, organizer pockets, and laptop sleeves I can fit the rest of my Ten Essentials everywhere I go. Your hands are busy and over loaded pockets are annoying. We all need more than we can carry, or at least we wish we had more than we carried.

5. Knife/Multi-tool No one said that there couldn’t be overlap between the lists. Trust me, if you have a Leatherman multi-tool or a Benchmade pocket knife you’ll find a dozen uses  everyday to use it. With the multi-tool you can get a bit more specific on your possible applications.  I carry my Benchmade everywhere I go and it saves me a whole lot of hassle.

6. Headlamp- Another backcountry essential, and I own four of them. Flashlights are all but dead to me. Most all scenarios including changing a spare tire or navigating a dark house in a power outage require the use of your hands. I have a headlamp in my car and in a kitchen drawer at home in addition to the waterproof high lumen ones in the gear shed. My favorite, the made in the USA Princeton Tec, followed by some awesome Black Diamond models.

7. Sunglasses- If you didn’t lose them all the time you would probably already have these with you everyday. Add a pair of Croakies to your Native Eyewear and keep them around longer. These travel with me from the center console in my car to the protective case in my day pack. Another all-around essential. All Natives have Polarized lenses and a lifetime warranty.

8. Fischer Space Pen- What is the number one thing you ask to borrow? It’s pointless carrying a cheap pen in your pocket, it won’t work when you need it and it is destined to explode and ruin a pair of pants. The Fisher Space Pen has a pressurized refillable cartridge that writes on wet paper, upside down, in the cold, and doesn’t explode. Although a pen doesn’t make the top ten list  for outdoor essentials, it should make your list. Use it to journal, for mapping or have it in the case of emergencies.

9. Goal Zero Recharger- We know you have your phone everywhere you go amongst other gadgets. Just because you are in civilization doesn’t mean that you have a charger and outlet around every corner. Head to the park, walk to lunch, go to the game, or sit at the center bar table far from a wall, You can take a few charges with you at about the size of a pack of Life Savers and $40 (Switch 8).  I’m in favor of escaping to nature without the use of modern devices, but it would seem silly now of days to backpack without being able to make an emergency phone call. I guess you could hike with a carrier pigeon.

10. Sunscreen- I rely on the lyrics of Baz Luhrmann for my last essential:

If I can give you one piece of advice: wear sunscreen.

Again, a carry over from one list to another, but how can you deny the importance of sunscreen. We could generalize this to more of a toiletries bag including some standard hygiene items like the versatile Dr. Bronners. If Dr. Bronners could be used as sunscreen I think that would be the one and only final item, but it can’t do everything.

Now that you have your list, pack your day bag or commuter bag with your Everyday Ten Essentials and head out into the world knowing that you are prepared for any day! Be sure to Tweet us @RRTrails your Ten Essentials, #10EverydayEssentials. we want to know what makes your list!

You can buy any of your “Ten Essentials” or your “Everyday Ten Essentials” at RRT.

Disclosure: The Ten Essentials of any variety will not help you in the event you fall into a Shark tank, are being chased by a Mountain Lion, or are experiencing parachute failure mid drop.
