Only two skates in and so far so good. I'm coming from a pair of 44k's which makes the transition fairly easy as these models were launched side by side. Only difference is the stiffer boot.
So aside from the usual growing pains of breaking in a new pair of skates and the slight adjustment to the stiffer boot / new steel, they've been great. I can't honestly say if they're an improvement yet, but my set of 44k's needed to be replaced anyways.
