Our read
Editorial interpretation from the specs and what we know of this shoe — not lab-tested.
Ride

Firm, low-slung ride with a moderate 26/21 mm stack and 5 mm drop that keeps the platform quick and connected to the ground.

Fit

Standard width only with a snug, race-oriented fit; no wide option for runners needing extra volume.

Best for

Competitive runners racing shorter, faster trail and mixed-surface courses where low weight and ground feel matter.

Avoid if

You need rock protection on technical terrain, a stable platform, or cushioning for ultra distances.
