I bought these five years ago, but I've only used them a few times in the last few years because there hasn't been much snowfall. So, they're in good condition. These are "Sorel" lace-up boots, combining a nubuck leather upper with a rubber bottom. They are a women's model made with the same manufacturing process and materials as the men's version, but the last is made narrower to give a more streamlined look to the foot. They feature a replaceable 9mm thick thermo-plastic inner boot. The durable outer shell, finished with a vulcanized construction, firmly protects the feet. The outsole uses an aero-track sole, which is excellent for shedding snow.
