What causes a blister?

Most hikers are well aware of this frequent problem: the feelings of friction and heat that begin can quickly turn into a painful blister inside their socks.

Our skin is made up of three distinct layers: the epidermis, the dermis, and the subcutaneous layer. When friction occurs inside your shoes, these layers of skin come into contact and rub against each other. This force generates inflammation and separates them, creating a pocket of fluid. This fluid, called serum, serves to naturally protect the skin underneath.

It is important not to ignore the warning signs: as soon as you notice a friction point, it is better to take immediate action, especially if you still have a long way to go. If you manage to identify this spot before a blister even forms, it is recommended to take preventive measures. Indeed, if you let the blister develop, it may fill with fluid and cause intense pain inside your shoes.

The presence of red fluid indicates that even the capillary layer of the skin has been affected.

Blisters can arise for various reasons, including:
  • The wearing of shoes that do not fit your feet properly.
  • The presence of pebbles or pine needles inside your shoes.
  • The infiltration of dirt or sand into your socks or shoes.
  • Seams or folds in your socks.
  • Wet shoes due to rain, crossing streams, or snowy fields.
  • Excessive sweating of the feet.
Blisters can sometimes result from moisture due to sweating. If you have fragile, thin, and sensitive skin, these conditions are conducive to the formation of blisters. Steep ascents and descents as well as carrying a heavy backpack can also increase the risk of blisters, as they increase friction inside the shoe.

How to prevent blisters in your hiking shoes

However, there are positive perspectives... by following the appropriate advice and using proven methods. The most crucial element lies in wearing shoes that fit your feet perfectly from the start. If you feel the slightest friction when trying them on, even minimal, it is highly recommended to opt for another model. Also, remember to check the condition of your accessories, such as quality laces, essential to ensure optimal support and avoid friction that can lead to the formation of blisters.

Choosing the right shoe

It is essential that your shoes match the activity you have planned. The longer the distance to cover, the more crucial it is that your shoe choices match the terrain and weather conditions. Stiffer and sturdier shoes, with better insulation, such as mountaineering shoes, are specially designed for mountainous environments. They are suitable for climbing on rocky surfaces, but are not suitable for comfortable and energy-efficient walking. Moreover, these shoes are often excessively warm for reduced altitude use during the summer.

What are the likely outcomes if you opt for these shoes in summer? Your feet will sweat profusely, your skin will become moist and swell, thus increasing the risk of blister formation. The rigid structure of these shoes only exacerbates the problem by generating more friction.

Conversely, wearing shoes that are too light and flexible for demanding terrains can also pose problems. Check out our selection of hiking shoes.

Managing moisture to reduce blisters

Can I finish my hikes without blisters? This largely depends on the material of your shoes. Leather is simply unmatched in this regard! Compared to any synthetic material or functional membrane, leather offers high flexibility once worn. Additionally, its superior absorption capacity is a great help in managing moisture inside your shoes.

Waterproof membranes have limited utility during summer adventures or in warm regions. To optimize the absorption or evacuation of moisture from inside your shoes to the outside, a clear temperature difference between these two zones is necessary. However, this becomes counterproductive in hot conditions associated with a waterproof membrane. Your skin becomes increasingly supple and more prone to blister formation.

For most hikers, shoes that are not completely waterproof are perfect. Leather shoes treated with a waterproof silicone base without PFC will easily withstand light rain or puddles.

How to avoid blisters by taking care of your feet

A multi-day adventure can pose a real challenge for your feet. By following these small tips, you can anticipate the formation of blisters:
  • Keep your nails short: This task should be done before every hike. If your nails are too long or ingrown, this can quickly lead to pain and result in blisters.
  • Use blister bandages: If you know certain areas are likely to form blisters, it is recommended to place preventive bandages there before they manifest.
  • Opt for adhesive tape: To protect sensitive areas, you can apply medical adhesive tape to cover the affected regions. It is important to ensure that no folds are created when applying the adhesive tape.
  • Use anti-blister balms: These products can also reduce the risk of blister formation. They create a protective layer that prevents friction.
By following these simple tips, you can protect your feet from blisters during your multi-day hiking adventures. For those looking to equip themselves at a lower cost, discover our range of affordable hiking gear and enjoy your outings with peace of mind.

How a good pair of socks can help prevent blisters

High-quality socks suited to your needs make a huge difference. Contemporary functional socks are designed for durability and promote excellent moisture evacuation through their fibers. Some are even made of merino wool to avoid unwanted odors and keep your feet warm, even when wet. It is important to avoid cotton socks, as they retain moisture close to your skin, which can be detrimental. Don't forget to choose technical hiking clothing to complete your outfit and minimize the risk of skin irritation.

First aid: how to treat a blister

What to do in case of a blister? As much as possible, avoid puncturing it, as this could expose the skin to bacteria and cause an infection.

Early treatment of the blister is essential before it becomes too large. That is why preventive measures play such a crucial role.

Specific blister bandages play a protective role by distributing pressure and preventing friction between skin layers. For optimal effectiveness, choose a bandage slightly larger than the blister. Carefully clean the area around the blister, apply the bandage, and that's it!

In case of emergency, regular bandages and medical tapes can also help. If you only have adhesive tape on hand, that can also work, as long as the blister is not yet well developed. To avoid irritating the skin with the adhesive, you can slide a compress or tape between the adhesive tape and the blister.

The good news is that if you act quickly, treat the blister properly, and take care of your feet during your adventure, blisters should heal in a few days.

If your blister bursts on its own or if you decide to puncture it because it is too large or painful, follow basic first aid to prevent any infection:
  • Carefully clean the area.
  • Use a sterilized needle to puncture the blister (you can burn the tip with a lighter for 1 to 2 minutes).
  • Once the liquid is evacuated, dry the area and apply a bandage.
If the skin of the blister has detached, the process is a bit more complex. Treat the wound with antiseptic if possible. Otherwise, clean the area with clean or previously boiled (then cooled) water. Then cover it with a bandage. A special blister bandage would be ideal in this specific case, such as Compeed bandages, as it creates an airtight and waterproof barrier around the affected area.
