Merrell and Gramicci Reimagine the Moab for a New Generation in 2025

A collaboration that celebrates heritage craftsmanship and the spirit of exploration.

Merrell, the global leader in hiking footwear, and outdoor apparel pioneer Gramicci have joined forces to unveil the Moab 2 Siren x Gramicci, a collaboration that merges four decades of outdoor innovation with street-ready style. Launching October 24, 2025, in two distinct colorways Dark Earth and Citron this collaboration reinterprets Merrell’s iconic Moab silhouette through a fresh design lens that bridges trail performance with urban versatility.

Two Originals, One Legacy

Founded just a year apart Merrell in 1981 and Gramicci in 1982 the two brands defined the DNA of modern outdoor culture. While Merrell pushed hiking technology forward with function-driven design, Gramicci, rooted in Yosemite’s climbing counterculture, revolutionized apparel with innovations like the gusseted crotch and webbing belt, now staples in both outdoor and streetwear scenes.

This collaboration honors those shared beginnings while reimagining what it means to explore today whether on the mountain trail, the rock face, or the city sidewalk.

“Exploring outside has always been about movement, freedom, and discovery  whether on the trail, the rock face, or the city,” shared Richard McLeod.

Chief Marketing Officer at Merrell also shared, lPartnering with Gramicci, a brand that has shaped outdoor culture for nearly 45 years, allowed us to create something that celebrates our heritage while redefining what an outdoor icon can look like today.”

The Moab 2 Siren x Gramicci Built for Trail and Street

At the heart of the collaboration is the Moab 2 Siren x Gramicci, a hybrid shoe that blends Merrell’s Moab platform renowned as the world’s best-selling hiking boot with Gramicci’s performance-inspired aesthetic. The sneaker’s standout features include:

• Reinterpreted Siren Web upper for structural support and breathability.

• Suede and mesh overlays that balance durability with ventilation.

• Vibram outsole for unmatched traction on varied terrain.

• Merrell Air Cushion technology to absorb shock and enhance stability.

The shoe’s design merges outdoor function with cultural statement, evolving the “Mother of All Boots” into a multi-environment essential that speaks to a new generation of explorers.

“Gramicci was born from the climbing counterculture of California, where every design detail was about evolving movement and freedom,” said Stephan Wendler.

Global Creative Director at Gramicci, said. “This partnership merges our climbing roots with Merrell’s hiking legacy, connecting with the raw, messy, and real side of the outdoors.”

Design and Color Story

The Moab 2 Siren x Gramicci arrives in Dark Earth, a rich brown iteration inspired by the terrain of Yosemite, and Citron, a modern, city-forward take that nods to Gramicci’s global streetwear influence. Both iterations incorporate design touches unique to the partnership recycled materials, Lycra lining, and 50% integrated EVA foam enhancing comfort while lowering each pair’s environmental footprint.

The design evokes an exploration-ready mindset but remains rooted in timeless outdoor utility. Whether navigating trails, climbing routes, or city commutes, the collaboration encourages wearers to embrace adventure with style.

Where to Find It

The Merrell Moab 2 Siren x Gramicci will be available starting October 24, 2025, on Merrell.com, Gramicci.com, and through select global retailers. Each pair highlights the enduring appeal of craftsmanship built to move with purpose, reflecting a shared philosophy: heritage is only powerful when it keeps evolving.

A Redefinition of Outdoor Culture

In recent years, collaborations between performance and lifestyle brands have blurred the lines between functional and fashionable  yet few have done so with the authenticity of Merrell and Gramicci. This partnership is not simply about reworking a classic silhouette; it’s a statement about the power of movement, inclusivity, and the shared call to explore.

Built for those who see the outdoors not as a destination but as a mindset, the Moab 2 Siren x Gramicci celebrates more than movement it honors freedom, heritage, and a new era for outdoor culture.
