TrailRanked #5 in Trail shoes

Stable, roomy shoe for smooth trails; the stiff plate bothers some, and technical ground is weak.

Positive

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

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

Negative

Great on smooth West Coast trails, but at $260 all three are out: it lacks the lockdown and stability for off-camber or technical terrain. One tester: 'as a trail racer it just falls really short.' Another will wear it casually.

Positive

The best carbon-plated trail shoe on the market for him. It fits incredibly well, feels like a road shoe, and is more stable for its stack on technical trails than rivals. It doubles as a road trainer, which softens the price.

Blog · Doctors of Running – Matt Klein (DPT) · summarized

Positive

B+/A- overall: a ZoomX and Vibram trail super shoe with a comfortable upper and barely any wear at 45 miles.

Positive

This runner finished third in a UK trail half in the Ultrafly, finding the outsole grippy and the ride like a plush Vaporfly.
