Felt like this was a great shoe when I got it last year but not as durable as other shoes I have in my stable with more miles on them. An OK shoe, nothing special.

Can't understand why Nike messes with a great shoe. The Air Structure Triax has been a classic and was known for being able to accomodate wide feet. When they stopped making widths, they increased the toe box but it was still a little too tight on top. Even so, I rate this shoe a 4, down from a 5 for previous versions.

I like them very much! I have used them for 4 month, over 300 km (200 miles) in total. Mainly running on sidewalk, also in the wood. Got them from Nike trial van:) Another pair (I mean experience) I have is Skylon, but I have used them for some competitions only. Tallinn, Estonia

Good shoe. I'm 5'11" and 150lbs and a collegiate runner. The shoe has held up against 60mi per week with speed training involved to and done it without blisters or achilles chafing. Doesn't get the 5 stars due to the laterall lace tightening, Nike's done better with some other model's, like the earlier Motos. Interested to try the Gore-Tex version.

Best running shoes I've ever owned. I am a moderate pronator with lousy running mechanics. I am fairly large at 5'11" and 200 lbs. and run about 30 miles per week in addition to cycling (not in this shoe of course) about 100 miles per week. I highly recommend this shoe and will buy several pairs with my next purchase in fear that Nike will change the design.

Very nice shoes. I like the cushioning. If you were medium thick socks, 1/2 size up may not be enough. Whole size would be better. The front overlay was also a little bothersome at first. Overall however, I am very pleased.

First, I would give 4.5 stars. If the fit in the instep area was improved, then it would get a 5. Second, RRS gives the weight at 12.7 oz and Nike at 13.0 oz. On my scale, I got 11.9 oz and I recalibrated twice to check accuracy. Cushioning is Great! Forgiving and responsive. The stability is secure yet the shoe is flexible and very smooth. I am very impressed.
