I've gone through at least 8 pairs of the 1123, this new replacement is absolutely awful. The sizing is totally different, we sized me in the NB store and made adjustments from the 1123. I have painful toes, now bruises/blisters on the small toes and worst yet,heel spurs back, neuromas irritated and I biff it constantly. My ankles roll over and I biff it. The entire time I wore the 1123's all of those issues were literally resolved. With my aetrex and the nb1123 I was no longer in pain. I honestly feel so ripped off by these shoes, and mortified that I have to try to find another brand now to hopefully get me back to pain free. I've now purchased two pairs of pricey nb shoes to replace the 1123, and I'm in foot misery.....I'd almost say these are like wearing a heel, the "rollbar" in the 1123 was legit, I seriously never rolled my ankles again. The rollbar in this shoe? Pointless.
