Blisters are a sack of fluid that form in the upper layers of the skin and the feet, in particular, are more prone to blisters. They occur due to internal structures rubbing, ‘Skin shearing’, which causes small tears under the skin which fill with fluid. A warm, moist environment as well as ill-fitting shoes can contribute to skin shearing leading to blisters.
Blister prevention
Socks
Correct fitting socks, padded socks to reduced pressure and materials that help absorb the moisture away from the skin, for example Moisture-Wicking socks.
Lubricants
Applying lubricant to reduce ‘rubbing’ forces for example Vaseline.
Shoes
Well fitting shoes; in length, width and depth.
Skin Toughening
Gradually building up resistance of the skin cells.
Taping
Aids in reducing shearing forces however this can be different from time to time; person to person.
Biomechanics and Arthotics
The way you walk and run can make you more prone to blisters; see your podiatrist for an assessment and management.
