Went out on a 5 mile club hike last Sat. after 2 miles started on a blister, 1 mile more the other heel started. Good boots just did not fit right. Hobbled in the rest of the distance, feet still hurt 5 days later. So I've got a blister issue. My point is, I think I'm going to do blister prevention by taping my heels to begin with , even before I get a blister. probably with cloth 1st aide tape, wont hold moisture the way duct tape would. Your opinion ??
