An 8mm drop helps lift you up on your toes during steep hikes, with adaptive lugs that ensure your footing stays firm. “Adaptive” describes how the lugs form the outsole’s tread—square studs line the heel and toe for grip on landings and push-off, while 5mm-deep multidirectional arrows stabilize the foot at the middle of the gait cycle. This design allows the shoe to adapt with both the changes in your stride and the ground underfoot. Like all Merrell’s trail running shoes, the outsole construction is all Vibram rubber. The Nova uses a specific variety called TC5+ that is especially noted for its grip across wet surfaces and extreme temperatures. The RW Takeaway: The Nova doesn’t skimp on traction, cushioning, or durability (despite its modest price) and is well-suited for wet terrain and trails of moderate difficulty.
