INOV-8 Trailfly Speed M - Men - Black / Red - size 8.5- model 2025 8.5

GRAPHENE-GRIP Rubber Outsole: 4mm GRAPHENE-GRIP rubber studs are carefully positioned in multiple directions to improve grip, shed debris quickly, boost propulsion off your toes and help you brake at the heel. The graphene-enhanced rubber has also been improved to give extra grip in wet conditions, when compared to previous models. POWERFLOW PRO Midsole: A bouncy, cushioned ride that retains high levels of responsiveness is provided by the new POWERFLOW PRO foam midsole. This amazing underfoot comfort and propulsion is built in a way that still allows for the ground-feel you need when running over uneven, hazardous terrain. Air-Mesh Upper: A single piece of air-mesh material, making the shoe highly breathable, comfortable. Over the top of the air-mesh, thick MET-CRADLE strips connect the midfoot to the heel, creating a locked-in, secure feel when you tighten your laces. BOOMERANG Footbed: Preserve your energy on long runs with the BOOMERANG Footbed. The insoles feature hundreds of foam beads that compress and spring back for 40% energy return during your stride. Perfect for longer runs where maximising every bit of energy counts. Anatomical Fit: The TRAILFLY SPEED hugs the natural contours of your foot, locking you in at the heel and then widening at the toes. This anatomical fit allows your feet to splay and feel the ground, while still giving you that secure feel that you need on technical trails.
