This is a durable waterproof boot. This means that water doesnt go IN and that also means sweat cant evaporate easily. I have narrow feet with a bony heel that chews up most boots and shoes, except for these danner shoes/boots designed to prevent that. since Ive had a great experience with how well danners kinetic tactical boot fit my feet, ive been trying to find a leather casual boot made by danner that would fit my feet the same way. Protect my feet, well fitting, no blisters/hotspot, last a long time. This is it! Broke in quickly, built to last and great for wet/cool/muddy/casual jeans situations.
