I ordered a pair of Asics 2130 running shoes from Zappos.com which turned out to be slightly short. Since I do more outdoor walking than running, I decided to order the Asics 2130 trail shoes instead, and was surprised to discover they are not the same shoe. The running 2130 is on the left, whereas the trail running 2130 is on the right.
The 2130 trail shoes are much wider than the Asics 2130 running shoes. The Asics 2130 trail shoes are much deeper than the running shoe version.
And the Asics 2130 running shoe is shorter than the same length 2130 trail running shoe.
Once again even though both shoes have the same name and outsole design, they are entirely different shoes. Make sure you thoroughly check the different version of the same shoe, because more and more, they will not be the same.
