Nike ACG Ultrafly Trail

Raced in the first version of the Ultrafly's and thought these would have been an improvement to them. I'll give it to Nike that these are a super snappy shoe with a great upper fit. The Vibram outsole is grippy as well -- no issues there. The main issue I'm having with them is the midsole is even stiffer than the first version! I've gotten 30 miles in the shoes so far and am hoping that it's just a break-in issue, but my feet are so sore after running in these that I cannot fathom doing any ultramarathon distance race in them, especially on technical terrain.

I'm not a trail runner. I will not be running in these. As a casual wearer, I love these shoes because they solve all of my issues with the Original ACG Mountainfly. First, the Ultrafly Trail dispenses with the rubber toe cap of the Mountainfly, which results in way more toe freedom in exchange for reduced protection. Second, the Ultrafly Trail has a slightly wider toe box than the Mountainfly, which allows my toes to spread more comfortably. Third, the squared off edges of the Ultrafly Trail's midsole/outsole offer greater stability and control of the bouncy midsole than the Mountainfly's rounded edges. Finally, the Vibram outsole is a clear upgrade over the Mountainfly's tread. As for the bounce? I am elated that the bounce feels exactly the same as the ACG Mountainfly. The bounce of the foam, and the stiffness of the carbon fiber plate are sublime. I haven't felt a shoe like this since the ACG Mountainfly. I could take or leave the looks, but the feel is unmatched. This is the update to the Mountainfly I've been waiting for.

THIS Nike ACG Ultrafly Trail Racing Shoe IS NICE WALKING ON. IM 63 GOING ON 64 AND LIKE THIS NIKE SHOE FOR WALKING IN THE PARK . THE SHOE IS EASY GOING AND COMFORTABLE. I LIKE THE NO LOGO NIKE SWOOSH ON THESE PARTICULAR GREEN COLOR. I WOULD OF LIKE A LOOP IN THE BACK OF THE SHOE TO HELP YOU PUT THEM ON BETTER .AN ALL BLACK COLOR WOULD OF BEEN A GOOD SELECTION TOO.
