Do Wet Socks Cause Blisters

Blisters are of many types. They describe a condition where pockets filled with fluid grow on the top layer of one’s skin. If not treated, they can cause further injury. Foot blisters are common among athletes, especially those who run for long distances. The Journal of Sports Medicine in 2004 concluded that 39% of runners have this condition.

Foot blisters occur from repetitive movement whether it’s running, walking, jogging etc. Freezing, contact dermatitis and some shoe types can cause blisters. However, what many people don’t seem to realize is that wet socks can also cause foot blisters.


The body produces sweat when running to cool our skin through evaporation. But, with shoes on, they prevent cooling from taking place effectively. Therefore, leaving your socks and feet wet.

Now moisture increases friction between one’s skin and socks. Although too much friction allows movement of inner tissues, it limits skin surface movement.

This causes a shearing effect that creates a physical separation between these two layers hence creating a void. When this void fills up with liquid, it forms a blister.

Cotton socks specifically can increase this condition compared to wool or synthetic socks. That’s because cotton ones absorb sweat. Hence, they expose your feet to longer periods of dampness, which can increase blister formation.


Choosing the right socks can, therefore, help prevent blisters from forming. If you’re looking for a reliable store to purchase your socks, see on amazon. Remember to confirm the material as well as purchase a good fit.

But as you do that, one should bear in mind that even advanced moisture-wicking pair of socks can still cause blister formation. Getting a good pair is your first step.

Next is to ensure that you change into fresh ones once the pair you’re wearing become sweaty. This, therefore, means that if you’re a frequent runner, you should have many pairs of socks to change up.

Again, your shoes also play a significant role in preventing blister formation. So, along with good socks, ensure that you wear a well-fitting pair of shoes and avoid running on wet areas.
