For Spring/Summer 2026, Merrell expands its design-focused Merrell 1TRL program with the introduction of the Agility Peak 6, a trail running model engineered for long distances across rugged terrain and positioned within a broader seasonal collection built around the theme of Modern Heritage.
Within the Merrell portfolio, the 1TRL line functions as a platform where the brand revisits established outdoor footwear designs through updated materials, construction methods, and contemporary finishes. The Spring/Summer 2026 collection continues that approach by combining archival silhouettes with layered textures, experimental material combinations, and visual references that draw from traditional craftsmanship while introducing more directional aesthetic treatments.
Across the range, several silhouettes reinterpret familiar Merrell footwear platforms while incorporating updated structural elements and surface detailing. Uppers frequently combine open mesh structures with netted textile patterns and suede or leather components that reference heritage outdoor materials. These traditional elements are contrasted with contemporary graphic treatments, including the lace-inspired “2 Tone Torn Camo” pattern that appears throughout the collection and introduces additional texture and visual movement across the surface of the footwear.
The seasonal palette reinforces this balance between past and present. Darker heritage tones and woven textures are paired with lavender-tinted greys and brighter Wisteria accents, while core neutrals including black, off-white, and grey ground the collection.
At the center of the season’s performance offering is the Agility Peak 6, a model designed to function as a dependable tool for trail runners navigating unpredictable terrain. The shoe builds on Merrell’s trail footwear lineage with an emphasis on traction, stability, and energy return across extended mileage where surfaces and conditions can shift throughout the course of a run.
The upper combines mesh, synthetic materials, and TPU elements arranged to balance breathability with structural durability. In high-stress zones, 3D print and TPU overlays reinforce the construction to improve abrasion resistance when moving across technical terrain. A 100 percent recycled breathable mesh lining sits inside the shoe, treated with Cleansport NXT technology for natural odor control, while a bellowed tongue construction helps prevent trail debris from entering the shoe during use.
The platform supporting the Agility Peak 6 centers on a FloatPro midsole, designed to deliver responsive energy return during long-distance efforts. A forefoot rock plate protects against irregular ground conditions, while FlexConnect technology allows the shoe to adapt to changes in terrain while maintaining stability. Traction is handled by a Vibram MegaGrip outsole equipped with lugs engineered to improve grip while shedding debris as runners move across varied surfaces.
The Agility Peak 6 launches as part of the broader Merrell 1TRL Spring/Summer 2026 lineup, which includes both new silhouettes and reinterpretations of several established Merrell footwear franchises.
Among the most recognizable of these is the Moab 2 Remix 1TRL, a model that revisits one of the brand’s most enduring trail silhouettes. The Remix introduces a reimagined upper built from molded suede leather with full-grain leather trims and breathable mesh inserts, creating a layered construction that emphasizes material contrast. Asymmetric lacing adds both structural support and visual distinction while preserving the underlying design DNA of the Moab lineage.
The platform retains the familiar Moab sole architecture, incorporating a molded nylon arch shank alongside a lightweight EVA foam midsole intended to support stability and comfort during outdoor use. Traction is provided by a Vibram Ecostep Recycle outsole, constructed with 30 percent recycled rubber and designed to deliver dependable grip across both wet and dry terrain.
Another model in the collection, the Relay Web 1TRL, draws inspiration from Merrell’s early-2000s Sprint footwear family. The silhouette features a low-profile design built around a full-grain leather upper and oversized Merrell “M” branding, combining track-inspired references with construction elements suited to everyday wear.
Interior components include a 100 percent recycled breathable mesh lining and a removable EVA foam footbed paired with a recycled mesh footbed cover. A rubber outsole that wraps around the heel provides traction across a variety of environments while reinforcing the shoe’s structure.
The Jungle Trek Mule 1TRL takes a different approach, adapting Merrell’s Jungle Moc heritage into a slip-on silhouette designed for everyday movement. The upper uses breathable mesh construction layered with the “2 Tone Torn Camo” pattern used throughout the collection, introducing visual depth while referencing lace textiles and traditional motifs.
An 80 percent recycled neoprene collar allows for easy entry while maintaining a secure fit. Cushioning is delivered through a FloatMax foam midsole, while FLEXconnect grooves incorporated into the midsole promote natural foot movement and enhance ground connection. A sticky rubber outsole provides traction across varied surfaces.
Alongside these new introductions, the Spring/Summer 2026 lineup continues to include performance-focused models from Merrell’s Merrell Test Lab (MTL) program.
The MTL Skyfire 2 represents the pinnacle performance offering within the range. The shoe is built around a Matryx woven upper constructed from Kevlar and high-tenacity polyamide threads, forming a lightweight single-layer textile engineered to maximize breathability while increasing durability and reducing stretch.
Inside the shoe, a temperature-regulating mesh footbed cover and tongue lining work together with an EVA foam footbed to support comfort during long-distance runs. A BZM-8 engineered flex plate adds protection and performance, while a dual-density FloatPro foam midsole provides cushioning and responsiveness. A Vibram MegaGrip outsole completes the design, delivering traction across both wet and dry terrain.
The MTL Adapt 1TRL continues alongside it as another performance-driven trail model. The shoe combines a Matryx upper with TPU overlays positioned in wear zones to improve durability while maintaining breathability. Additional details include a padded collar, reflective elements intended to increase visibility in low-light conditions, and an elastic lace keeper.
Cushioning is provided by a FloatPro foam midsole designed to enhance both comfort and energy return, while a Vibram MegaGrip traction-lug outsole supplies grip across mixed trail conditions.
Across the Spring/Summer 2026 lineup, the 1TRL program continues to function as a design platform within Merrell where archival outdoor footwear concepts intersect with contemporary materials and evolving construction techniques. By combining technical trail running tools with reinterpretations of established silhouettes, the collection reflects an approach that connects the brand’s historical outdoor foundation with updated performance technologies and modern design language.
Within that framework, the Agility Peak 6 extends Merrell’s trail running lineage while anchoring a broader collection that moves between technical performance footwear and lifestyle interpretations drawn from the brand’s archive.
