In short

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

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

Runners find the Speedgoat 6 firm and stiff, with solid grip and a stable platform on rocky, technical trails.
