When Sorel's design is added to the mix, the result is comfortable in both wet and cold winter conditions. - Waterproof design - The upper has 100g/m² insulation under genuine leather - Microfleece lining - Midsole provides shock absorption - Evertread rubber outsole offers good grip even in winterthe material does not harden in the cold - The teddy trim at the top of the boot is not only stylish but also helps keep snow out
