This lightweight trail shoe from Mammut is designed for fast mountain running. The sole is quite stiff but adequately cushioned, there is a 6mm drop from heel to toe, and it includes a rock plate to stop sharp stones causing discomfort. The grip is excellent on rock and gravel, and better than expected in mud considering the shallow tread depth. The upper is light but uses a memory foam collar and a honeycomb padded tongue to create a comfortable fit. The stiffness of the sole combines with the stability provided by the heel cup and lacing system to create a very sure-footed racing shoe.
VERDICT: Light, stable and precise for high-speed mountain running.
