In short

Runners find the Agravic Speed Ultra fast on smooth, non-technical trails and it gives a strong, propulsive ride.

Runners like the roomy toe box and cushioning, even on long trail runs, but the added heel pillow put off several.

Plated, protective ultra shoe with a roomy toe box; unstable for some, and weak on technical ground.
