Comments: Great shoe, I switched after the kinvara 4's took a turn for the worse. An amazingly fast shoe that is supposedly a racing shoe, but doubles as a trainer. At first I feared that they may wear out quickly, but I was very surprised to see that they have lasted a long time both in terms of performance and simple physical appearance. I am very happy with this shoe.

Comments: This is the best shoe i've ever put on!!! I'm a sockless 6ft 165 lb runner with medium width feet, and the fit is amazing(i was concerned they might be very narrow). The combination of the light weight, glove fit, and thin responsive outsole makes this shoe cry out for speed. I haven't had them long enough to comment on long term performance or durability, but I'm already planning to buy up several pairs in case they are changed for the worse like my favorite kinvara ones have been. I did not upsize: I wear 11.0 in every shoe, and the 11.0 in the A6 fits perfectly: snug and hugging but still with enough room everywhere. I think the recommendation on upsizing probably stems from the forefoot volume, which I would simply choose another shoe if you have a wide foot rather than size up. If your foot shape is compatible this is one killer shoe. It begs to go fast!
