Because treating blisters underneath the foot is more laborious, takes longer, and is more delicate than preventing their formation, Epitac Sport offers Epithrliumtact 01 technology in the form of an anti-blister gel for the foot (especially the heel), which acts as an anti-friction dressing. Why ruin a hike or stop a run because of a blister? Knowing your weaknesses and the most common injuries of your sport allows you to take precautions before the damage is done.
