Blisters are fluid-filled pockets in the outer layers of the skin, which usually form when the skin is damaged. The fluid protects the tissue below by cushioning it, also allowing the damaged area to heal. The most common cause for blisters on feet is friction, or rubbing against the skin from wearing uncomfortable, stiff or ill-fitting shoes. They often occur when skin is moist in addition to prolonged walking or activity. Solon Footcare offers products that prevent blisters or soothe and promote healing when blisters occur.
