Is anyone else having problems with the RC DC insoles? They're perforated (have holes in them) and seem to be causing blisters on my forefoot. I've tried about 5 different socks (nike elite, dri-fit, injinji, power sox, etc) and they all cause blisters after about 8-9 miles. Has anyone had any luck with replacing the insoles (don't know how they're glued down) or even filling the holes w/ shoe goo?
