Description from backcountry.com:
You take things to a new level every time you strap your board to your feet. So why shouldn't the bindings you use to strap said board to said feet take things to the next level, too? These Ride Men's Delta MVMT Snowboard Bindings are part of Ride's specifically-for-boundary-pushers DFC line, and they style you out times infinity. And as for performance, well, chew on this: The Delta MVMT DFC features the Movement Chassis System, which is cored for a crazy light weight, provides 360 degrees of freestyle flex, and doesn't scrimp on responsiveness. Landlite EVA shockpads smoothly absorb impact on those rooftop acid drops, and the Flexlite highback's design amps up your heelside control.
Condition: These bindings are actually amazing, the only reason that I am selling them is because I outgrew them. There are not many signs of wear on these, just some rubbing on the upper straps. Function like new. Hate to see these go but hope someone else will enjoy them.
Their sizing chart says Medium fits up to a size 9 in mens. The heel would probably be snug with a 9.5 boot but the straps would be more than long enough to accommodate. Basically comes down to how bulky the boot you are wearing is. Hope this helps!
