A Guide to Healthy Hiking Feet: Hiking Foot Injuries and Foot Care

When your feet get injured out on the trail, there's nothing worse. This guide catalogs all the different foot injuries you can encounter, how to treat them, and how to know when it's time to seek medical attention.

There are a lot of injuries that us hikers can inflict on ourselves out on the trail, but most of them are avoidable or treatable. In this article we’re going to cover the most common foot injuries that hikers can incur while out on the trail, how medical science deals with them, and how hikers deal with them.

The following foot related injuries we’ll be covering are; Blisters, Blackened or Lost Toenails, Sprained Arches, Tendonitis, Trench Foot, Bone Spurs, and Plantar Fasciitis.

Note: None of the following information should be taken as medical advice! We are backpackers, not licensed doctors or nurses. In each section we will link you to the appropriate professional medical information, so that you can make a more informed decision on how to treat these common ailments.

We’ll be covering ways that we, ill informed hikers on medical issues, handle these problems, but you should consult a medical professional in person first and foremost.

(This article is a continuation of our “Backpacking and Hiking Footwear: Choosing Hiking Boots and Shoes.” There’s a lot of great information there to help you choose the right footwear which can cut down on your chances of injuring your feet.)

What are Hiking Blisters, How Do They Form, and How Do You Deal With Them?

Blisters are the most common foot injury for hikers and backpackers and form for a many reasons. Two of the main reasons are poor sized shoes that are laced either too tight or loose, or low quality material socks which aren’t wicking away moisture very well.

Blisters can be painful and even become infected if they’re not treated well. Home remedies can help ease the pain of blisters in most cases, and allow them to heal faster, but sometimes blisters can become infected and develop into something more serious if not taken care of.

Please follow this link to read up on blisters, and learn how to treat them the proper way from a more informed source before reading on.

Hikers that are out on the trail use all different methods for treating blisters and there are different ideas about how to treat them among the community. Some people think you should leave them alone for 24 hours before popping them, others believe you should pop them right away, while

It should be noted before you continue reading, popping a blister doesn’t hurt, and it’s in fact a relief to pop a blister since it often causes painful pressure under the skin.

Whether that’s a good idea to pop them is up to medical science though, and you should read the linked article above, but the ultimate risk for blisters is infection.

One method that people use to reduce the chances of infection is to heat up a safety pin with a lighter until it’s red hot, then pop the blister with the pin and rub antibiotic ointment or hand sanitizer on the wound.

Hand sanitizer should not be used unless you have no other options available since it contains alcohol which dries out the skin and makes the blistered area susceptible to more damage from friction.

Another method people use is to heat up a sewing needle with a lighter to purge off any bacteria, then they thread the needle with about six inches of thread, and coat the needle and thread in antibiotic ointment.

Then, with careful precision poking the needle through one side of the blister, and then out the other while cutting off the needle, there’s an inch or two of thread dangling from both sides which just needs a bandage over the blister to complete the process.

This works because the thread allows the interior to wick away the moisture inside the blister by following the thread and create a path for the antibiotic ointment into the wound at the same time.

Regardless of the method though people agree, if you start to feel a hot spot while you’re walking out on a trail you need to stop and stick a bandage, or a strip of leukotape, moleskin or duct tape, on the affected area.

It’s much better to prevent a blister by taking a break for a few minutes than deal with a massive and painful blister later which makes an entire day agonizing.

If you want to prevent blisters in perpetuity you need to wear toe socks. Toe socks will separate out your toes and force the friction onto the fabric and not your skin.

Blackened or Lost Toenails

Another common injury out on the trail is blackened or lost toenails. If you read through the sections on Backpacking and Hiking Footwear – The Ultimate Guide to Hiking Boots and Shoes, you’ll know that the primary the result of blackened, or lost toenails, is poor sized shoes without a large enough toe box, or gap between the tips of your toes, and the front of the shoe.

As you’re walking down a hill your feet will slide forward a bit and if your shoes have an improper fit your toenails will smash against the front of the shoe leading to blackened and sometimes lost toenails.

Another reason this can happen is because of untrimmed nails. Make sure you bring a pair of toenail clippers with you and maintain them often.

Please refer back to the section on How to Size Your Shoes where we describe how to avoid this injury in detail with the wiggle test, the thumb test, and the toe tap test.

Please read this article to learn more about Toenail Trauma, how to care for it yourself, how to manage pain, how to know when it’s time to reach out to a medical professional for assistance.

Sprained Arches

The result of torn ligaments in the muscles of the foot, sprained arches are the result of constant pressure and weight being applies to the arches of your feet for a long period of time. This is a serious injury and needs to be treated with respect.

You can avoid spraining the muscles in your feet by stretching, choosing gradual elevation to continue the hike as opposed to quick shortcuts, taking ten minute breaks every hour, and having the proper insoles in your shoes.

If you had the choice of either stepping up onto a rock to progress through the trail faster, or walking around the rock and taking a gradual incline, it’s always better to take the gradual incline.

Treat your body and feet well out on the trail since they’re taking the most damage and need the consistent and kindest care. You cannot treat your feet too well.

If you sprain your arches you have to take at least a few zero mile days, so don’t push yourself too hard and damage your feet.

Please read this article to learn more about Sprained Arches, how to relieve the symptoms, and when you should reach out to a medical professional for assistance.

Trench Foot

Most people know what trench foot is. It’s caused by having wet feet, cramped up in a cold boot, for a long time.

This environment causes your skin to become saturated with water and the tissue in your feet becomes damaged causing your nerves to react to the trauma on your body and you start feeling horrible pain.

A lot of people have had the beginning stages of trench foot form on their feet if they’ve ever had pruned or winkled feet that were sensitive to the touch. Beyond this stage your feet reach a terrible state, and you don’t want to experience it.

Once you’ve left your wounded feet in a wet environment for long enough blisters can form and without treatment your flesh will start to fall away and separate from your body causing permanent damage and potential loss of limb.

Trench foot can happen fast. In just twelve hours of wet conditions you can be in the medium to advanced stages of trench foot. You need to take this very serious out on the trail.

Even if the conditions are dry, but your feet are sweating bad you need to take your shoes off and dry out your feet at least twice per day.

There are very easy ways to prevent this horrible condition and you just need to be mindful of the condition of your feet to prevent it.

Bring [Talcum Powder] to dry your feet out, or the best way is to have plenty of moisture wicking socks to change into.

In general, if you start your hike in the morning, you’re going to want to take your boots off and switch into a dry pair of socks by lunch time. Then, leave your wet socks hanging off your pack to dry as you walk.

When you go to bed at night make sure you switch into a pair of socks that are dedicated for sleeping. This will prevent hypothermia and give your feet a chance to recover in a warm and dry environment.

If you don’t like wearing socks while you sleep, you need to start. It’s beneficial to your feet when you’re out hiking.

Please read this article to learn more about Trench Foot (Immersion Foot), what its symptoms are, what causes it, how it is prevented and treated, and how to know when you should reach out to a medical professional for assistance.

Bone Spurs

Twenty five percent of all the bones in your body are in your feet, so there’s a lot of room for bones to be damaged. When a section of a bone has grown to extend beyond its normal shape that’s a bone spur.

Bones are a hard living tissue, and a bone spur is formed by the grinding of bones which causes damage and triggers them to produce more bone in the area in order to protect themselves.

Most of the times bone spurs aren’t an issue, and unless you feel pain in the area, there’s no reason to mess around with them. There are surgical procedures that can remove bone spurs which you can see demonstrated in 3D by following this link, but for the most part bone spurs are not an issue.

Bone spurs occur for hikers because of constant trauma to the bones from stomping on the trail, and from poor muscle function due to a lack of stretching or nutrition.

Taking breaks, stretching to allow your muscles to operate, and having quality shoes with comfortable insoles, can prevent bone spurs from forming by reducing stressful friction on the foot bones.

Bone spurs can become very painful over time and become a big problem, so you should take your health out on the trail and pay attention to the way your body feels.

Don’t push yourself to meet mileage deadlines and allow yourself to relax at least a few times a day out on the trail. It’s not worth it to hurt yourself just to gain a few extra miles per day.

Please read this article to learn more about Bone Spurs, the symptoms of them, how they’re diagnosed, and how they’re treated.

Achilles Tendinitis

Tendinitis in hikers is more of times than not caused by high cut hiking boots rubbing on the Achilles tendon. If you read through the Backpacking and Hiking Footwear: Choosing Hiking Boots and Shoes article you’ll see a section which describes how to fit your shoes under “How to Break In Hiking Boots and Prepare Them for the Trail.”

In that section it describes how to lace your boots by leaving the top two lace hooks undone, tilting your knee forward about ten degrees to allow one finger to slide between the gap at the back of your ankle, between your Achilles tendon and the Achilles notch of the boot, then finishing up your lacing in that position.

Doing this allows free range of motion while walking and keeps your Achilles tendon from rubbing on the liner and heel cap of the boot. This will also reduce your chance of having blisters form on your heels.

Achilles tendinitis can also turn into plantar fasciitis since the tendon starts in the calf muscle and warps down around the heel into the bottom of the foot. So, stretching your leg muscles is very beneficial because it makes your muscles more elastic and reduces the chances of them being torn or damaged from constant use. Follow the link to this article to learn about leg stretches that can help you keep your body in good shape for hiking.

Please read this article to learn more about Tendonitis, how to care for it, and when you should reach out to a medical professional for assistance.

Plantar Fasciitis, Posterior Tibial Tendonitis, and Peroneal Tendonitis

When you’re out on the trail, you’re an athlete. If you’re carrying a backpack that weighs anywhere from 20-40 pounds you can look forward to burning about 500-800 calories per hour depending on your age, gender, weight, and height.

Since the average thru-hiker walks anywhere between 10-25 miles in a day on a trail that means calorie requirements, including the standard 2,000 per day, are anywhere from 7,000 to 22,000 calories to maintain normal weight.

Plus, since you’re sweating, you’re losing even more nutrients. So, maintaining proper nutrition is difficult, and requires almost constant consumption of food and water. If you’re not keeping up on your nutritional requirements your body will start to feel the effects and everything spirals out of balance.

In general, there are four reasons for foot pain, or any other leg pain out on the trail. Improper nutrition, inflammation, muscle tightness, or improper footwear.

With poor nutrition your muscles lack the proteins to repair and heal the tiny tears caused by the vigorous physical activity. The cells lack the carbohydrates needed to energize them, they lack the fats which carry vitamins throughout the body, they lack the vitamins to help fight against infection and carry oxygen, and they lack the iron to help that oxygen be carried and keep your muscles growing in a healthy way.

All of these nutritional deficiencies together cause your muscles to fatigue more which reduces their ability to stretch and causes tightness, which can then lead to inflammation.

Maintaining proper nutrition, and drinking a ton of water, is the cornerstone to keeping your muscles healthy. Finding a nutritional tracker app on your phone can help you follow your nutritional needs.

There are a few popular phone apps such as Cronometer, and MyFitnessPal which will allow you to type in the food you’ve eaten and see what nutrients you’re lacking. We suggest you check them out.

You can also check out this link here to see your nutritional needs in percentages.

Beyond nutrition there’s stretching. Foot pain often starts well above the foot in the calf and thigh muscles. Stretching your feet, ankles, calves, and thighs before, during and after a hike will help them be more elastic and reduce the chances of them tearing.

Please follow this link to see foot stretching exercises, and click on this link to see stretches for your legs and upper body. Stretching your upper body is also important for back which is carrying your backpack. You should view stretching with a holistic approach and stretch your entire body since everything is connected.

Next there is footwear. We suggest you go find a Dr. Scholls insole machine, or visit a podiatrist, and get insoles fit to the shape of your foot. This is one of the best investments you can make for yourself and it makes a world of difference. Please do this for your feet, you won’t regret it.

So, in summary, if you have proper nutrition, you’re stretching three times a day and drinking plenty of water, and you have good shoes with proper insoles for the shape of your feet, and you’re still feeling foot pain, you need to go see a medical professional. There is no substitute for having a doctor examine you. Don’t mistake a search engine for a medical degree.
