Looking for some advice. I have 2007 Burton Cartel bingings in medium and recently purchsed nitro Anthem boots in a size 8 to use with these bindings. My issue is that, I have too much room from side to side in the binding. When I tighten up the boot either goes to one side or the other. Should I get size small bindings?
That sounds a bit weird. I use Medium Burton bindings (3 different pairs) and have size 8 boots with no issues. The boot doesn't completely fill the footbed from side to side, but that shouldn't be an issue. I do up my toe cap first, make sure my foot is back as far as it'll go, then do up the ankle strap.
Can you try a pair of smalls without buying? Maybe a Burton demo day in your area?!?
