I had got the Cartels last year in a Large, and rode them for a season before finding out my boots were too big and had to switch to a medium. Dogfunk took care of it no questions asked! super stoked, love the bindings, they ride super comfy, good flex, love the skybacks. I haven't had the issue maybe but once about having to put the skyback down when getting on lifts (no problems in Mammoth). Definitely recommend them to anyone ready to step it up.
