Several HOKA trail running, hiking and all-terrain shoes feature a premium, lightweight GORE-TEX bootie designed to keep your feet dry and comfortable in a variety of conditions. GORE-TEX product technology consists of a waterproof membrane with pores smaller than a water droplet but larger than a water vapor molecule, meaning rain and snow can’t get in, but sweat can get out. So your feet can stay dry while you fly through wet and/or snowy environments – without overheating.
