I think I must have some deformed heels. I think every shoe I've ever hiked in gives me quarter sized blisters in a matter of 30 minutes. This goes for xc skiing also.
I've tried duct tapeing my entire heel/arch, bandaides, NuSkin paint on liquid bandages, 2 layers of socks (one being polypropelene), wool socks, cycling socks, shoe inserts expensive and cheap.
What the hell? I will sweat the NuSkin and duct tape off in 1 hour. No product of anykind stays put, even stuff my husband swears works for him when he plays hockey.
Someone suggested I fill my Vasque boots with hot water, let them soak, pour the water out, then walk around in them for day. I think this is the only thing I've never tried, and don't really want to!
