The base of this shoe is more narrow than the intuition 2.0. I have wide feet that swell on long run and prefer the 2.0. I really hope altra moves back to the original width. It feels more like the the torin 2.0 width wise- almost like altra used the same mold. Overall, it's a pretty good shoes, not as much heel or arch support at the 2.0, but it is light and responsive. As with all my altars I had to order a larger size. I wear a 9, but ordered a 9.5 and they fit great length wise.
