Blisters on the feet develop where friction, pressure, and moisture affect the skin.
What can toe socks do to help prevent this?
There is only one effective way to deal with moisture: reduce sweating and regulate moisture.
That sounds easier said than done. But why do humans sweat in the first place? Sweating is the body’s response to excess heat. The body releases water in the form of sweat, which then evaporates on the skin. Under normal conditions, this cools the body down.
In closed shoes, however, sweat cannot evaporate properly, so the foot does not cool down. And how does the body respond? “More sweat!”
In conventional socks, sweat remains on the skin between the toes. In toe socks, however, the fabric absorbs the sweat and binds the moisture within the material.
When we talk about friction in the context of toe socks, we’re mainly referring to friction between the toes. But what exactly is rubbing? In most cases, it’s moist skin rubbing against moist skin: toe against toe. Add to that sharp toenail edges, calluses from neighboring toes, or even a grain of sand that has found its way into the shoe.
Toe socks put an end to this friction. Each toe gets its own little fabric compartment — like a second skin that absorbs and reduces friction.

Yes, you read that correctly: reducing pressure is something you need to take care of yourself.
Choose well-fitting, comfortable shoes with plenty of room for your toes. Your toes are the fingers of your feet — they need freedom of movement to do their job properly.
Treat yourself to barefoot shoes. Barefoot shoes are ideal for your feet because they provide plenty of space and natural freedom of movement.
