Contemporary design and a double set of midsoles make Duality uniquely versatile – these shoes are ready for anything from a stroll through the park, to a mountain expedition. Haglöfs Duality will adapt to the terrain, no matter what the conditions are. One set of interchangeable midsoles, with a green pair of sole that provides robust support for rockier trails and heavier loads, and a red pair of sole that is lighter and softer, for a more relaxed feeling. You always have the option to switch half-way – but you'll never need to bring those extra shoes along for the hike. The modular design process for Duality was driven by innovation, with a focus on durability, repairability and versatility for a long product life. The shoes are made from responsibly-sourced materials.
