Description
For FW26, the MTL Adapt RPT reinterprets the croc-print identity seen on 1TRL lifestyle icons Moab Remix and Jungle Trek through a distinctly performance-driven lens. Engineered in the Merrell Test Lab, it delivers an elite trail running expression that balances elevated design with uncompromising technical precision. Built to perform at the limits, the shoe pairs Flexconnect™ cushioning for responsive, adaptive underfoot comfort with a Matryx® upper woven from Kevlar® and high-tenacity polyamide, providing exceptional durability, lightweight structure, and breathability in a single-layer construction. Underfoot, a Vibram® Megagrip outsole ensures confident traction across wet and dry terrain. The result is a refined, premium trail runner that fuses 1TRL design language with MTL-level performance.
