Science of blisters

Miles speak louder.

★★★★★
Used this to protect some hot spots I developed on my last hike. Worked great and kept them from turning into blisters. This is a permanent item in my hiking pack now.
★★★★★
It stays put even through him playing several games, he says he can’t even feel it after a few minutes of putting it on and best of all NO MORE BLISTERS!
★★★★★
I used this as mostly preventative tape whilst walking two Camino’s. It prevented rubbing and my feet survived the constant pounding day after day for over 500km.
