It depends on your activity level, specificapplication, and terrain. Many ENGO users have gone 300+ miles on one patch,the recommended interval for replacing athletic shoes. Replace patches when thetop layer wears through (the backing will show �white�) or when your patchpeels away from the footwear material.
When installing ENGO Patches in the back ofyour shoes, use caution when slipping your foot into your shoes each day toavoid accidentally peeling the leading edge of the patch with your sock. Wrap abit over the edge of the shoe to help it stay on or use a shoehorn if needed.This will help maximize the lifespan of the patches, keeping you inblister-free comfort for a longer period of time.
