Merrell Men's Chameleon 7 Limit Waterproof Hiking Boots - Lightweight & Durable Outdoor Shoes for Trail Walking, Camping & Mountain Trekking

I have owned many pairs of Merrell shoes and boots, of various types, and have always found them to run a little bit small. Usually I order a half size larger than my size to compensate. Even at that, these Chameleons are a very snug fit. With normal socks, it just prevents them slipping, but it would be impossible to wear heavier hiking socks with them. Suggest you possibly go a full size larger than your usual size.
