i guess you didn't read what he bought. Mission bindings are not low quality. wayyyyyy better than anything from Ride hahahahahahahaha
to the OP, wear just the inners around your house. I'm in the process of breaking in a pair. At first, just start with short time periods. Don't let it get too painful otherwise you'll develop a bruise that won't heal til the season's over. Sounds like your bindings should be warrantied (which you're doing) and maybe your boots too.
You're joking right? Nothing Burton makes matches the quality of Ride and Rome bindings. Most of their stuff is overpriced garbage. Basically anything under 200 dollars from Burton sucks and deteriorates fast. It's all right to have your own opinion, but Missions are pretty low quality.
