Binding sizing to boot size
So I'm looking at a Ride RX size L (9-11) binding. I wear a size 11 boot. I am aware that the true size of a boot varies a lot between brands, but what about mondo sizing? The Ride website shows that size L fits 27-29 CM boots, and my boot is a 29 CM boot. Does that STILL not assure me of being able to fit O.K. in a size L binding?
On another note, does the weight of a binding increase with size enough that I would notice?
thanks for any input you guys might have.
