The mens Trailfly G 270 is a trail running shoe designed to be suitable all the way to ultramarathon distance, with more cushioning and a wider fit. The Trailfly G 270 features a Graphene enhanced rubber, which manages to blend incredible durability and yet retain flexibility and light weight. For the first time, Inov-8 built a shoe with zero heel to forefoot drop, which helps to promote the best possible posture and form even when you’re getting tired.

The Inov-8 Trailfly G 270 is the new name for the Inov-8 Terraultra G 270.

Improved use of Graphene-Grip

Graphene-enhanced rubber cleats repositioned in key areas and flex grooves fine-tuned for agile sticky traction that lasts even longer.

Extra Grip in the Wet

4mm deep cleats all now armed with water dispersion channels and rubber dimples to give even better grip on hard wet trails.

Plusher Ride

New POWERFLOW MAX foam delivers improved cushioning that retains its full shape and optimum level of performance for twice as long. A 3mm increase in stack height further enhances underfoot comfort.

Snappier Bounce

The new foam also gives 20% more energy return for a snappier, bouncy feel with every stride, even deep into an ultramarathon.

Additional Spring

Unique BOOMERANG insole features hundreds of tiny beads that compress and then spring back for 40% more energy return than previous insoles.

Enhanced Comfort

New ADAPTERFIT technology allows the fit of the upper to adjust to natural movements and swelling of the foot when running long distances. Redesigned lightweight tongue and wide toe-box further aid comfort.

Improved Durability

Stronger upper materials retain soft feel but give more protection and durability, plus a smoother feel on the inner.

Graphene is the world’s strongest material. We are the first – and only – brand to use it in sports shoes thanks to a partnership with Graphene experts at The University of Manchester. It delivers the world’s toughest grip – insane sticky traction AND increased durability, no compromise.

Midsole & Insole

New POWERFLOW MAX foam delivers improved plush cushioning that retains its thickness and optimum level of performance for twice as long. A 3mm increase in stack height (from 9mm to 12mm) further enhances underfoot comfort.
The new foam gives 20% more energy return than its predecessor for a snappier, bouncy feel with every stride – perfect for tired legs deep into an ultramarathon.
The new foam uses a blend of elements, with a higher percentage of TPU (Thermo PolyUrethane) than the TERRAULTRA G 260 for increased energy return. Greater anti-abrasion properties help maintain the thickness and optimum performance for longer.
Unique BOOMERANG insole features hundreds of expanded TPU beads that compress and then spring back for 40% more energy return – and greater cushioning – than previous insoles. Tested to retain its thickness and optimum performance level for longer.

Upper

New ADAPTERFIT technology allows the fit of the upper to adjust to natural movements and swelling of the foot when running long distances. Redesigned lightweight tongue and wide toe-box further aid comfort.
Stronger upper materials retain a soft feel but give more protection and durability, especially around the edge of the forefoot, plus a smoother feel on the inner.
