Verdict from 3 experts and 5 user reviews

8 reasons to buy

  • Grippy: Nike ACG Mountain Fly Low has a hawkish outsole that prevents wearers from slipping. 
  • Hard-wearing: The rubber material that wraps the bottom and above the tip of the shoe is durable. 
  • Bouncy cushioning: The Nike React foam element in the middle layer is squishy and reduces any form of pressure.
  • Smooth ride: Its Vaporfly tech right below the forefoot almost lets you fly. It helps ease the forward push on every step.
  • Secure fit: Its lace system even wraps the back of the shoe for a lockdown fit. 
  • Reflective: Shiny reflectors that flash on the shoe's heel and side make one visible along dark roads and trails. 
  • Convenient: Among Nike's slip-ons, it’s one of those that pose no struggle slipping in and out of. 
  • Breathable: A perforated fabric takes up the place of Gore-Tex, making this shoe more ventilated than the high-top waterproof version.

2 reasons not to buy

  • Rigid: Because of the amount of rubber in this sneaker, it doesn’t flex as much.
  • Heavy: It is far from being light with lots of detailing present in it. As per one reviewer, it weighs less than the Adidas 4D Fusio

Bottom line

Nike gets innovative with its hiking-inspired kicks under the ACG line by tossing in the ACG Mountain Fly Low. Whether you want a slip-on that will get you covered on a tight day or one that's fitted for outdoor exploration, this shoe will give you both without cutting back on comfort and support. Its aggressive design works well on smooth and rugged surfaces and lightly wet, snowy, and muddy terrains.

Nike ACG Mountain Fly Low: A tough one even without GTX

Made with an aggressive sole, the rugged hiking-inspired Nike ACG Mountain Fly Low won’t keep you confined within the city. While it’s designed with an ultra-cushioned sole that offers tons of comfort, it taps your adventurous side as well to go exploring the outdoors. The waterproof Gore-Tex layer is stripped off to make its cover light while preventing your feet from getting sweaty and toasty.

Low-top Mountain Fly against similar styles

  • Nike ACG Air Terra Antarktik, designed after winter jackets, is as trendsetting as the ACG Mountain Fly. Both are wrapped in durable, water-resistant ripstop nylon and a sole that grips on different surface types. Terra Antarktik's high-top is lined with Gore-Tex, making it a bit pricier than the Mountain Fly Low.
  • Nike ACG Mountain Fly Gore-Tex is the high-top hiker version that comes with a sock finish. If you prefer a pair that will hold you down in snow or rain, go for the ankle-high. But if you want more breathability, the Mountain Fly Low will give you that. The GTX won’t come lightly to the wallet than its slip-on sibling, given its technical features and height.
