Merrell

Merrell Test Lab (MTL) is an official line established by Merrell as an incubator for product development, creating cutting-edge footwear intended to be tested by athletes. The official website describes it as the place where the most technical, category-shaping ideas emerge, indicating a flagship role at the core of performance development, distinct from the design-focused orientation of Merrell 1TRL.

Merrell 1TRL is a design-led derivative line officially offered by Merrell, positioned as a series that reinterprets archival silhouettes and combines performance with contemporary practicality. The brand treats it as a new expression of the brand and describes it as presenting Merrell’s values to a high standard. Within the lineup, it has a distinct role from the core hiking and trail styles and Merrell Test Lab, serving as an entry point centered on contemporary heritage.
