I purchased these boots in March this year and have used them only once thus far. The boots are well made and appear to be strong and are comfortable to wear (no wearing in required). The only problem I found was the sizing to be a little off. I'm a 14 US in a running shoe and found the Simms vapor 14 to be half a size to one size too big even with my waders on. I have fixed the problem by wearing an extra pair of socks and have inserted an extra inner sole with arch support. This has done the trick. So I do recommend them just 'try before you buy'.
