Salomon's INDEX.03 is more than just a running shoe, it's a bold statement in sustainable design and circular production.
As the latest model in Salomon's INDEX line, it continues its mission to create high-performance products with minimal environmental impact. Engineered for recyclability, the INDEX.03 merges environmental responsibility with the needs of everyday runners.

Designed for Disassembly and Recycling
At the core of the INDEX.03 is a modular design that allows for easy disassembly at the end of the shoe's life cycle. The upper is crafted from polyester, while the bottom unit is made from thermoplastic polyurethane (TPU). These materials are selected specifically for their recyclability and ease of separation. Once returned, the TPU sole can be repurposed into other Salomon products, such as ski boots, and the upper fabric can be recycled into textiles.

Improvements Over Previous Generations
Compared to the INDEX.02, this new model incorporates several important upgrades. The production process has been refined to reduce waste, bringing down material offcuts during manufacturing. The tongue of the shoe is now made from 100% recycled polyester, and the use of undyed fabrics further minimises environmental impact. Despite these changes, the shoe weighs just 249 grams, offering a lighter and more agile running experience.

Performance-Driven Features
While sustainability is a key focus, the INDEX.03 doesn't compromise on performance. It includes an InfiniFOAM midsole that provides soft, responsive cushioning and is fully recyclable. The outsole uses Salomon's Contagrip technology to deliver excellent traction on various surfaces. The reverse camber geometry encourages a smooth, rolling stride, helping runners maintain efficiency and reduce fatigue during longer sessions.

A Simple, Global Recycling Process
Salomon has made the recycling process easy and accessible. Each pair of INDEX.03 shoes come with a QR code on the tongue. Scanning it registers the shoes online and allows users to print a prepaid shipping label. The shoes can then be returned to a local drop-off centre, where they are sent to Salomon's designated recycling facilities across Europe, North America, and the Asia-Pacific region. This system makes it simple for users to close the loop.

The INDEX.03 isn't just a running shoe, it's a forward-thinking solution that signals the future of responsible footwear.
