Loving these shoes so far. I've been using them for steep bouldering and sport climbing and have no complaints.
I sized them 0.5 EU smaller than my Katana Laces and they fit perfectly. Unlike the Katana Laces, the Geniuses did not need any break-in time (fit tight but comfortable straight out of the box). At least for me, the Genius has a better heel too.
