I got the boots and the size for my foot fits really really well, but I do a lot of walking and hiking so my calves and lower leg area are larger than most. These fit really really snug at the very top where the draw string is. They are designed for people with extremely thin legs so if you work out, or are thick, these will more than likely not fit around your leg. Rather than returning them I will be cutting a V into the shank to give my leg some breathing room.
