Comments: Nice shoe but same durability issues. I love the roomy toe box but the heel is a little loose. I wish the heel fit was similar to the Superior which is a bit tighter. I was hoping for more miles but it seems that the upper will disintegrate soon. I roll my right foot a little to the outside and the lateral edge is now beveled and wearing quickly as I have reached the foam. Definitely not what I was expecting. Be forewarned: the fit will lure you in with its roomy toe box and the ride is comfortable but not plush. In the end, though, you will have to resign yourself to fewer miles than anticipated. Well worth the entry price but definitely not a long term investment.

Comments: the Instinct 1.5 didn't feel much different than the Instinct 1.0, but like many others have said, tore the outer mesh after 80 miles. Also doing much more aggressive street runs with 400-600ft elevation change so they do take a bit of abuse but I am looking into the provisions now. HOPEFULLY a bit more support.

Comments: Nice shoe, a bit heavy but comfortable. The mesh tore after 150 miles and now I have rips on both sides. Other reviewers made the same comments on the Altra website, but oh so strangely, they were taken down.

Comments: First, I want to say that I love these shoes. However, the upper is like tissue paper in terms of durability. I had the 1.0 and they lasted about 400 miles. I got the 1.5 and the upper started tearing at about a hundred miles. The store replaced them and the next pair did the same thing. I am now wearing these shoes with duct tape around the uppers (I'm at a hundred and fifty miles). There have been many reports of similar problems with this shoe. Until they fix the upper, don't buy this shoe.

Comments: Awesome shoes. Bought these a month ago and have replaced all my other running shoes. The adjustment for the zero drop was very easy. My legs feel much better at the end of runs with these shoes than conventional shoes. The zero drop and limited cushioning really provide the feedback to run with a more efficient stride which is why I think I feel so much better at the end of runs.
