I was disappointed in the 1540v2. The 1540 was a much better shoe. The 1540v2 seems to be cheaply made. The sole under the toes is not as thick as the 1540. I chose the same size as I'd wear in the 1540. This shoe seems to run narrower in the toe box and wider in the heel. I had to really tighten the shoe laces to keep my foot from sliding with each step. It's a shame that New Balance ever started improving a good thing. The 1123 was the best shoe and they've only succeeded into ruining it. I'm most likely going to look for a different shoe. I can't recommend this shoe due to size issues and poor craftsmanship.
