Thanks a lot for your help I just ordered the union atlas, just hope the toe cap works with my Nike Kaiju if not I will have to change it like you recommended.
I've ridden the Kaiju for the past couple seasons with the Atlas. I'm a 10, and the M/L fits perfectly.
Not sure what the commenter above is talking about with lack of adjustability? Grab some other bindings off the shelve. Union is as adjustable as anything out there.
