Sorel Caribou Leather Kaufman Rubber Snow Boot - Men。These Sorels have hardly been worn. I believe them to be a mens size 10, but there isn\'t a size printed on them. They are waterproof with a removable ThermoPlus inner boot. Rated to -40 degrees F Faux Fur trim Features seam sealed waterproof construction and 0.098 inch bonded felt frost plug midsole. Per the manufacturer these boots are often imitated, but never equaled, the original SOREL boot features waterproof construction, seam-sealing and a removable felt inner boot for warmth, comfort and protection in unexpected weather.
