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.
FLYSPEED Pro Midsole: Fly over the ground with the super critical (nitrogen-infused) FLYSPEED Pro foam midsole. This hardwearing foam provides a great balance between cushioning, ground-feel and stability over uneven terrain. Ideal for when you need sustained comfort and support when ticking off big miles.
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.
Choice Of Fits: The TRAILFLY ZERO hugs the natural contours of your foot, locking you in at the heel and then widening at the toes. Available in Standard Fit and Wide Fit. Go Wide Fit if you have wide feet or would like more room when running longer distances.
