These bindings are of a completely different design than anything in use today. They offer positive steering control and extreme durability. They are very quick to put on or take off. Your boot is held in place with two nylon straps with infinitely adjustable spring buckles. These bindings are in use by the Maine Warden Service and professionals who make their living on snowshoes. They attach to the snowshoe with two screws per side that are supplied. Note: order by the winter boot size you will be wearing. Lifetime warranty on all UHMW parts. http://snowshoe-bindings.com/
