Don't use with GORETEX
Reviewed by Soprisette from Carbondale, Co. on Saturday, December 1, 2012
After researching & buying these inserts for my husband, I opened them up to find a disclaimer for boots with waterproofing membranes. As I bought them for his GORE-TEX work boots, I was really bummed. Apparently the tough material on the bottom of the heels can rip the membrane. I wish that info would have been available on the product info before buying them. I cannot say anything about the insets themselves, just diappointed info wasn't there.
