Positive

Handled very technical trail races; durability and protection like the Salomon Genesis but more breathable and bouncy.

Positive

Two 50Ks: practically perfect apart from being too stacked for very technical terrain; grip and response left after 500 km.

Blog · Better Trail – Alex King · summarized

Positive

The upper and midsole are strong: after ~400 mi there's only cosmetic pilling, and the foam still feels good. The outsole is the big problem. Lugs wore down across the whole sole until it's close to bald, and wet, muddy or snowy traction is only average and worsens with wear. Too pricey for a daily driver.
