It’s hard when you have to walk in soft snow with your snowboard or skis, but here’s a solution. The Small Foot snowshoes created by Bulgarian company Any Exit have been specially designed with for backcountry snowboarders.
When deflated both snow shoes fit into a small bag with a pump for inflating. Once you inflate them, a set of straps on the snow shoes allows them to be attached to your boots. Great solution and they are very portable.
