Why Sandals Cause Blisters
Blisters form when friction, moisture, and pressure irritate the skin. Sandals with loose straps, stiff edges, or poor arch support increase rubbing. Materials that trap sweat and straps that sit in the same spot during walking are common causes.
Features That Help Prevent Blisters
Look for sandals with soft, smooth linings, adjustable straps, and a secure heel cup. Cushioned insoles and arch support reduce pressure points. Breathable materials and moisture-wicking footbeds keep feet dry, which lowers friction.
How to Choose Blister-Free Sandals
Try sandals on later in the day when feet are slightly swollen. Walk on different surfaces to check for slipping or rubbing. Break in new sandals gradually. For more guidance on blister prevention, see the American Podiatric Medical Association's foot care tips at https://www.apma.org/foot-health.
