Trail shoes need to be comfortable, yes, but also adaptable to changing conditions. Nike's ACG Mountain Fly 2 Low was developed with this in mind. The multi-material upper combines supportive rubber on the extended toe cap and sidewalls with rip-resistant yet breathable fabric. A foam midsole combines with a lightweight plate running from the ball of the foot to the heel to provide necessary cushioning and added support. Mountain bike-inspired tread ensures sure footing even on wet, muddy surfaces, and the lace toggle enables quick adjustments on the go.
