Nike  ACG Ultrafly 2 Trail-Running Shoes

I just ran a 50km race with 5,000 feet of elevation gain and loss wearing these shoes. I was nervous that the toe box height would be too short, but that didn’t end up being an issue at all. I didn’t get a single blister after getting them from other trail shoes. The front toe shield definitely saved my big toe more than once after slamming into some rocks. I’d recommend them for lighter mud and snow conditions, but overall they were very comfortable and fast. They fit true to size to my vaporflys. Very satisfied and an eye catching piece.

Incredible trail shoe from Nike…well balanced shoe with a great lockdown. The zoomx is much softer than its predecessor but still offers the connection a trial runner needs from foot to ground. The sole is quite aggressive but you don’t feel it running on tarmac or light trail which is really important to me. I took just under a minute a mile of my pb for a coastal run wearing this shoe, it blew me away. The colour is a lot brighter than the pic and really is an eye catching wear…11/10.

Amazing shoe on trail. It doesn't feel heavy and has a great solid platform to help with stability.

Forward propelling with solid grip that’s fine on tarmac as blades are short. Wide front footprint like original invincible and original vaporfly rear. Great uphill. Basically bin all your legacy trail shoes.

Comfort, style and beauty. Not to mention performance! The color on these shoes is remarkable. They are stable, have good bounce to them and the grip is fantastic.

Trail runs are my new favorite. These add stability and spring to my step when running. Highly recommend for trail running.

Very comfortable excellent shoes 👍

My first run with these today. Ran a 3 mile trail single track loop that I typically run 4 times/week. New shoes always give me a placebo effect but my perceived effort was less than previous runs and I was 15 seconds per mile faster in these ACGs. They felt awesome out of the box on this non-technical single track. The price is a little steep for a pair of trail runners but they are plated, lightweight and well built. I was impressed. Nike treated me great. This was my second pair. I had one run in my previous pair and the Zoom X foam had a tear near the heal. My first run out was on a technical and rocky trail so not sure if I hooked a rock or something but they took my return and sent me a new pair very quickly and easily. I will use these ACGs on smoother single track and save some more robust shoes for rockier technical trails. Can't wait to get some more miles on them!

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.

The shoe is an update to the original Ultrafly, a very stiff carbon plated “trail “ shoe. If you want a stiff shoe for mild terrain, this is it. Really wish Nike would get away from the stiff plates in their shoes, I returned this item. Refund was received very quickly.
