Anti-blister socks, also known as blister prevention socks or non-blister socks, are specially designed to help reduce friction and keep the feet dry. They typically use moisture-wicking fabric as well as design features such as seamless toe construction to help reduce chafing.
Foot blisters are primarily formed when intense friction causes a tear between the layers of the skin, which then becomes filled with fluid. Sweaty feet and moist or ill-fitting socks can contribute to the formation of blisters. Anti-blister socks help combat these issues and decrease the chance of blisters forming.
