Nike ACG Ultrafly Trail

7,349,000₫

Ultralight foam and enhanced grip fuel your trail speed.

The Ultrafly Trail takes what you love about the original and refines it, so you can go the distance. The springy ZoomX foam is more responsive and the full-length carbon plate is softer for a smooth ride. The outsole helps reduce weight while maintaining enhanced grip as the miles pile up.

ZoomX foam

Ultra-responsive ZoomX foam midsole delivers Nike's highest energy return with a stable feel for the trail. The foam is 'unwrapped' in the heel for even better responsiveness.

Breathable Mesh Upper

Don't worry about puddles or streams—the upper is made for water drainage. It's also lightweight, durable and breathable.

More flexibility

Tackle technical terrain with the full-length carbon-fibre plate. We reduced the stiffness compared to the original Ultrafly for better control on the trails.

Enhanced grip

Go the distance with Vibram® Megagrip outsole. It's designed to give you durability and enhanced grip on wet terrain.

  • Amazing trail shoe.

    TomW644103353

    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.

  • 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 preference. The cushioning is superb. I have a tender nerve on the ball of my foot, and I walk/jog 3 miles a day. The cushioning in these shoes has kept me able to do that, whereas other shoes I have - even those with a good amount of cushion - aren't comfortable right now. I'm of normal weight and not a long-distance runner, but I'm enjoying them so far.

    I love the new color iv been waiting for one that is actually red for a long time. my favorite color is red and I just did not like when they made one orange and called it hyper crimson.

Lightweight speed, grip and energy return, come hell or high water.
