The Youth Whitney Short Lace from Sorel are warm, waterproof and quick to put on and take off - just right when it's cold and wet outside. The waterproof polyamide outer material is supported by synthetic overlays coated with polyurethane and a waterproof and breathable membrane. The footbed can be removed, and the synthetic insulation and fleece lining keep the boots warm down to minus 32 degrees Celsius.
