GRAPHENE-GRIP RUBBER OUTSOLE 4mm GRAPHENE-GRIP rubber studs are positioned in multiple directions to enhance grip, remove debris quickly, improve propulsion off your toes and aid in braking at the heel. The graphene-enhanced rubber provides extra grip in wet conditions compared to previous models.
POWERFLOW PRO MIDSOLE The new POWERFLOW PRO foam midsole offers a cushioned ride with high responsiveness. This underfoot comfort and propulsion still allows for ground-feel when running over uneven terrain.
AIR-MESH UPPER Constructed from a single piece of air-mesh material, the shoe is highly breathable and comfortable. Thick MET-CRADLE strips connect the midfoot to the heel, creating a secure feel when laces are tightened.
BOOMERANG FOOTBED The BOOMERANG Footbed features hundreds of foam beads that compress and spring back for 40% energy return during your stride, preserving energy on long runs.
ANATOMICAL FIT The TRAILFLY SPEED follows the natural contours of your foot, locking in the heel and widening at the toes. This anatomical fit allows your feet to splay and feel the ground, while still providing a secure feel on technical trails.
