I went to Breck & Keystone w/ them... I think the small size of binding is a bit too small for my size 8 boots... It takes a lot of effort to get my foot in or even taken out... I'll take them to the local shop and see if they can help me with it.
I'm going to Whistler in less than 1 month, I guess I'll have to go to a local trash hill ski area to test out both again and decide if I should bring my old binding or the K2 cinch I got :'(
Another issue I ran into in CO was that my heel & ankle kept on lifting up from my boot when I'm riding toe side,...
Your new boots are tight? The bindings are too tight and causing numbness/foot pain? Too tight on the toe? Too tight on the ankle?
I assume you've got the straps backed out to the maximum and then when you cinch up the back they are too tight. If that's the case you need a longer plastic ratchet piece. A local shop would have some.
Your new boots may also need to be broken in.
I could be wrong and someone may have better advice.
