Take your favorite hiking shoes add some serious insulation and style and you've created the Sorel Women's Waterfall™ Low Lace Snow Boot. And for added protection not found on all hiking boots the upper is a waterproof suede seam sealed to maintain a toasty interior even after stepping off the curb and into a deep puddle of slush. Low bulk Thinsulate™ wraps the top of the foot and ankle in a cocoon of heat trapping coziness while underfoot an EVA midsole and footbed provide cushioning and insulation. For rough snow and ice covered terrain the Sorel Waterfall™ Low Lace Women's Snow Boot includes a fiberglass shank for torsional rigidity and a lugged outsole that maintains flexibility and traction in severe cold. The Sorel Waterfall™ Low Lace Snow Boot for women is rated to -25º F (-32º C) during active use.
