Nike  ACG Ultrafly Trail-Running Shoes

I’ve had these now for a while, and have run on essentially three types of terrain. Roads, (gravel and paved) well maintained trails, and very technical rocky trails. The shoes have been amazing on the less technical stuff, and I have set a few pr’s with them. On the more technical descents I have rolled both ankles multiple times. Thankfully I have strong ankles and only once did it actually leave me with a mild strain from the inversion. The stack height and cushion is phenomenal on more predictable surfaces, but is not super safe for the ankles on the technical stuff. That’s my experience, and I would absolutely buy them again! Use them for the right job.

Well, everything you’ve read up about the Shoe of like when you first get the Shoe that it needs to work in. Well that is 100% accurate shoe fits great nice and comfortable a lot of cushion. Well, I put over 30 miles on them already and when I first started running the 1st mile it had a little tightness, but you know 2nd mile it kind of got a little better now I’m really starting to dig the shoes. I definitely would highly recommend them. Of course I know they’re pretty pricey, but just look at most shoes out there and the shoes living up to the hype running on terrain getting off the concrete. Need a good shoe for that and this shoe is definitely a great Shoe.

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.

I had big expectations on this pricy shoes but am terrible disappointed. They’re not as comfortable as I thought they would be not much overall cushion leave me with knee pain at the end of my runs, I find the wild horse 10 more comfortable and more heel cushion than this more expensive shoes.

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.

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. It’s a comfortable, well cushioned everyday trail trainer as well as something you can push for a pb in. The carbon plate is not intrusive and with faster/longer strides really returns something extra. Cut a minute from my 10k pb two weeks into using them. Construction is solid, comfort is excellent. Super stable, grippy on grit and loose surfaces. I take a size 9 in regular shoes but always order half a size up in running shoes and that’s perfect for these too. My road running shoes are Vomero Plus and they too have full ZoomX but feel nothing like these at all, these are way more stable and less marshmallowy in their cushioning.

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.
