SIDI Canyon Gore Boots
Produced with top-grain leather and shammy split-grain leather on the boot leg. Lined with GORE-TEX® membrane, the boot instep features a replaceable micrometric SL lever and closure strap.The SL lever may be used in two ways: more than one click at a time for an immediate lock, or half a click at a time for an excellent micrometric adjustment. The grey flaps can be pressed together to unlock completely or alternately to loosen the fit gradually.
Replacement parts available. SIDI boots are a narrow fit and they recommend going up a size from what you would normally wear.
