My elementary school-aged daughter used these for only one season. KEEN.DRY (Waterproof and Breathable Material) KEEN's unique waterproof and breathable material prevents water from entering while allowing moisture inside the shoe to escape. Toe Protection (KEEN.PROTECT) Thick black rubber covering the toes, with the outsole wrapping up to the toe, securely protects the toes from rocks and ice. High Insulation The upper part (the fabric covering the instep) is puffy like a down jacket. This includes the insulating material KEEN.WARM, designed to retain body heat and keep you warm even on cold days. Easy to Put On and Take Off No need to tie shoelaces; you can easily adjust the fit and take them on and off, even with gloves on.
