You get what you pay for in these boots! Stable, beefy and comfortable not to mention tough. There is no membrane such as as gortex but this thick leather is scuff resistant and waterproof if not soaked for long periods. It is a high cut but the leather cut out above the heal gives a great range of motion without discomfort with snug ankle support. The full shank allows for heavy loads carried. The vibram sole and rubber rand are of the highest quality as is the leather. Use nixwax to waterproof it better as again it is a boot with no waterproof membrane. A better spring to fall mountaneering boot. Used up and over whitney, forester pass, mt charlestson, redrocks, sierra nevads and so on. They rock and will last if you take care of them! The soles grip like a GMC Hummer! Medium to narrow fit....
