I bought the 156 indoor which has a 251 waist. My boots are size twelves and they fit, luckily. I'm sure putting 11.5s on a 24.3 isn't going to work though. The midlife lost is the exact same as the indoor except it's a tiny bit wider, not even enough to qualify as a wide board, and has the inserts slightly wider. But it might not come in your size.
