Bought a pair of 2160's last October and have loved them. I recently saw them onsale due to the release of the 2170's so I decided to buy two more pair. As soon as I received them I knew right away something was wrong. I put the new ones next to the old ones and right away I could see they were not manufatured the same. While they had exactly the same marking and design on the top of the shoe, the soles were different. My old pair had a flared sole around the edges which is typical of running shoes, while the new ones had a sole that was flat all around the shoe. You can see that this effected the toebox which is more narrow on the newer pairs. I then ordered a pair of Gel Cumulus 13 and guess what? There was the flared sole again, not to mention plenty of room in the toebox. Hey ASICS, how about some manufacturing consistency?
