Typically, there are 3 differences between a boot for hikes vs. one for snow:
Snow boots are often taller, coming up higher on the calf or even to the knee
Snow boots have different treads to handle ice and snow rather than dirt, gravel, skree, etc.
Snow boots will have more insulation and, often, heat reflecting insoles
Snow boots are also often waterproof, or at least water resistant.
Stay tuned... in addition to our collection of hiking, walking and casual boots, Xero Shoes has a snow boot coming out in the 2nd half of 2020!
