I have a pair of Spirit 4's which I really like, but I'm looking for something beefier to drive fatter skis. Do you know the flex of the Spirit 4, so that I can compare it to the Mobe? Also, I"m confused about what bindings this boot works with. I have some Dynafits, which I know it will fit. How about regular alpine bindings? Thanks!
The Spirit 4 is a 110 flex with the ski tongue (90 flex with the walk tongue) Both the Spirit 4 and the Mobe are compatible with all alpine touring bindings including tech style bindings. Neither are compatible with alpine bindings.
