Awesome Pair

Amazing pair of shoes. I’m a frequent runner on the road and trail (light to mild terrain). Very stable on the heel and very light. The shoes have energy return and you can feel it. It wants you to go faster. I have put in 30 miles and it feels great. Will buy another pair.

My new favourite shoe!

Love these! Stable, grippy, comfortable and FAST!

I'm running 20km+ on dirt, gravel, grass and tarmac. Nothing too technical, its Surrey hills basically.

The wide forefoot is good for me. The heel and the lacing are secure, I get a good hold in the heel without having to do a runners knot.

Amazing trail shoe.

Fabulous trail running shoe.
I run 5-10k trail runs three times per week, so a fairly amateur runner. I have been using the Pegasus Trail 5 and Peg 4 GTX mainly this year which are both great shoes. I wanted to try these due to the full ZoomX, carbon plate and Vibram sole. I was hesitant because a lot of the reviews online (incorrectly) paint this as a focussed race shoe only. It’s not.…

Love the color!!! Wide toe box and narrow vamp, GREAT cushioning!!!

The turquoise is beautiful. I wish there were more athletic shoes in this more monochromatic color style. I removed a star due to what I consider a quite wide toe box, yet relatively narrow vamp - and due to this, sizing down wouldn't be an option. I also prefer a cloth material as opposed to this thin whatever-type material, (I realize this will propel water more) but that's just a personal…

The shoes are spectacular

These shoes are phenomenal. It took a little break in period but they absolutely sing. I’ve done multiple trail races including a 50k in them. I have over 280 miles on them and they still have pop and feel bouncy and fresh. The toe box is a perfect width. The stability (compared to the ACG zegama) is a little worse, but nothing to be concerned about. They are fast and have held up extremely well.

Big improvement over last years Ultrafly

The shoe has a very nice bounce to them when running and the fit is really good. Plenty of room in the toe box kept my feet comfy. I like the way the upper is made because it hugs the foot and does not let in small stones and dirt. Last years Ultrafly let dirt in like crazy and it’s really awesome Nike fixed this. Also all the color ways are really nice looking. I really like the blue color that I bought.
