Launched in April 2025, the TRAILFLY™ MAX and TRAILFLY™ ZERO are built with the same natural-fitting foot shape as the TRAILFLY™ and TRAILFLY™ SPEED, both launched in 2024.

The four shoes make up our TRAILFLY™ Series, built for runners who want to run naturally over hard-packed trails. The super-comfortable design is complemented by an agile underfoot feel that brings grip and trail connection, together with lightweight cushioning and protection.

TRAILFLY™ MAX

The most deeply cushioned and perfect for longer distances. It replaced the TRAILFLY™ ULTRA G 280 and TRAILFLY™ ULTRA G 300 MAX.

TRAILFLY™ ZERO

Our zero-drop option, perfect for those who enjoy the ultimate natural running experience. It replaced the TRAILFLY™ G 270 V2.

TRAILFLY™ - THE SERIES

  • TRAILFLY™ MAX 6mm drop, 35.5mm/29.5mm stack, 300g
  • TRAILFLY™ 6mm drop, 29.5mm/23.5mm stack, 280g
  • TRAILFLY™ SPEED 4mm drop, 22.5mm/18.5mm stack, 270g
  • TRAILFLY™ ZERO 0mm drop, 23.5mm/23.5mm stack, 270g

Both the TRAILFLY™ MAX and TRAILFLY™ ZERO share the same 4mm lugged, GRAPHENE-GRIP rubber outsole pattern as the TRAILFLY™ and TRAILFLY™ SPEED but have different midsole foams and upper designs versus the 2024 launches. Graphene, remember, is the world’s strongest material.

The TRAILFLY™ MAX and TRAILFLY™ ZERO have a new FLYSPEED PRO midsole foam. This is a supercritical, nitrogen-infused EVA foam – our highest performing foam to date. It’s super-lightweight, while giving both greater comfort and superior energy return.
