The noSno Soft Bindings is a system specially designed to give a full locked binding without the highback and with maximum adjustment for use with trainers or walking boots. These have 2 ratchets over the top of the shoe and a heel ratchet around the back so you are fully locked to the board.
These bindings mount onto the standard 4 hole snowboard binding hole pattern. This is on many top end boards but if this is not on your board then you can drill this but please check it does not invalidate any warranty.
For maximum ankle support/protection and control we recommend high back trainers or walking boots with these bindings.
