Let us present: Sorel Caribou, The Original. This boot can withstand really low temperatures, it is warm, comfortable and waterproof. The boot has a warm ThermoPlus lining that is removable and there is a 2.5 mm frost plug in the midsole. The outsole is equipped with friction studs to minimize the risk of slipping, in other words you stay warm, dry and safe in winter. To keep you really dry and warm, it is good if you think about how you dress underneath; we recommend a functional or wool sock for the best warmth. When you have used the shoes, we recommend that you remove the inner shoe and set it to dry, in this way you protect the shoe against wear and you will also keep the heat better when the inner shoe is properly dry.
