Most snowshoes have adjustable bindings that are technically one size fits all. However, some bindings don’t fit all large men’s winter boots so be sure to check. Because a snowshoe might be rated for certain shoe-sizes, it doesn’t necessarily mean that they will fit your winter boots. Snowshoes are also sized based on individual weight ratings. They’re meant to provide a certain amount of flotation that supports a certain bodyweight. If you’re heavier, you’ll generally need larger snowshoes.
