Rated 4 out of 5 by from altra instinct 4.0 Bought these to replace my very worn out merrell vapor gloves. I wanted something with zero drop but a bit more cushioning. The Altra 4.0 size a bit small I recommend a 1/2 size up. I also recommend you lace them with the Altra lacing pattern makes a big difference in your foot placement overall.

Rated 5 out of 5 by from Love Instinct 4.0 This is my first pair of Instints, 5th pair of Altra running shoes and they are my favorite road shoe to date. Ready for a long run out of the box. Nice heal counter and wide toe box for natural splay. I prefer the moderate cushion to the Torin's high cushion. It is just enough for the higher mileage when your fatigued and form begins to slacken. Would recommend to anyone.

Rated 5 out of 5 by from A great update, maybe the best overall Altra. A firmer ride and more substantial outsole than the Torin 2.5, which is also an excellent shoe. A return to the design and feel of the Instinct 3.0.

Is this really a trail shoe? I think you're website has this mislabeled as such.

It is a road-running shoe.

 I am buying this for my son as a gift. He takes a 13. Do they run true to size?

Asked by: Xpstoy
Based on feedback and reviews, these shoes have been known to run true to both length and width.
