I like this shoe a lot so far, in fact it's my favorite pair of running shoes I currently have. It may be my choice for a 100 miler I am doing, but still feeling it out and I plan to try some other shoes as well. So far in my training I've done 14 miles at once on these and didn't have any major issues. Typically I get a size 7.5 in running shoes but the 7 seems to fit fine. In street shoes I wear 6-7. The white color obviously gets pretty dirty running in the trails, and I'm in the PNW with a lot of mud, but comfort means more to me than appearance

Trail Speed
For the first time in Nike Trail Running, we implemented a carbon Flyplate, layered between ZoomX foam and a knit fabric-wrapped midsole, to give you propulsive energy and a springy feel. It helps you stay fresh to continue pushing the limits of speed, whether you're at mile 1 or mile 50.
Traction for Various Conditions
Slimmer and lighter than a traditional outsole, the Vibram exclusive Ultrafly outsole made with Vibram Megagrip has a sticky rubber that works with a chevron lug pattern. They combine to provide grip on both uphill climbs and downhill descents, even in wet weather. This exclusive outsole also features Vibram Litebase and Traction Lug Technologies. The result is a lightweight, durable outsole that gives you great grip wherever your run takes you.
Stable on the Trail
A flat bottom and minimized cross rocker give you optimal stability on trail terrain while the heel-to-toe rocker provides a smooth transition. Specifically engineered zones of support in the midfoot give you a secure, yet lightweight feel while weaving through the trail at a rapid pace.
Durability Where You Need It
The fabric wrap on the midsole helps to cushion the foam from the elements and abrasion of being on the trails. Hard-wearing abrasion-resistant materials provide durability.
More Benefits
- Vaporweave mesh on the upper provides breathability.
- Foam midsole adds cushioning.

Wish there was a 4.75 option.... I think Nike has come very close to nailing it on this one. Love the light materials and durable sole. Love the wide toe box, because that is where your landing power is (widest part of foot, greatest surface area, energy return). Love everything but the drop. Miss the low profile of the Terra Kiger (6 maybe?). Perhaps an unpopular opinion, but I love the light, bright colors. Reminds me of my legendary coach questioning the dark colors, as (some unknown) research he cited showed that people perceive dark colors as heavier. Yes, they will get dirty on the trails, but so will the mud-colored ones. I say that it runs big, but actually true to size. It's just that with the wide toe box (amazing), you don't need to size up!
