Ultrafly

After wearing out two pairs of Ultrafly 1s, a runner bought a third.

“I just wore out my second pair of Ultrafly 1’s and opted to pull the trigger on a third pair”

A runner with over 400 miles on the Ultrafly used it up to a 50-miler: stiff but bouncy and propulsive.

“I’ve used this up to a 50 miler and I enjoyed them.”

At 500 km, a runner calls the Ultrafly the best shoe they've owned for moderate, flat trails, with an insanely good upper and shape.

“Best shoes I ever owned, for moderate and flat trails.”

A runner calls the Ultrafly 1 one of the worst trail shoes they've owned, even at $99.

“The Ultrafly 1 is one of the worst trail shoes I have ever owned.”

A runner loved the Ultrafly as a road super shoe for marathon training, though it's not great on trails.

“one of the best super shoes I’ve ever used for marathon training”

An Ultrafly 1 owner loves it on serious alpine routes when fast and dry, but not for mud or long, slow days.

“I love my pair and have done some serious alpine routes on them.”
