The new XTRM 2 is improved in every way over the original, giving you extra grip, stability and durability for the toughest terrains and conditions. Still made for demanding middle-distance runs in extreme conditions, it features a reshaped last and a slightly rounder toebox, giving your toes more room to move. A responsive CMEVA midsole combined with a rock plate adds protection and torsional rigidity without sacrificing agility. A new racing tongue is secured on both sides to prevent shifting, while the new lighter Fitlock system locks the foot at the arch for a secure, customized fit. The softer heel cap reduces pressure on the Achilles, and a special traction fabric inside the heel prevents slipping during movement.

The upper is made from Swiss Schoeller Keprotec®—an ultra-durable, abrasion-resistant material that doesn’t absorb moisture, keeping the shoe light even in wet conditions. It’s also bluesign®-certified, ensuring sustainable and responsible production. The updated outsole pattern delivers unbeatable grip in all conditions. The Superior Contact rubber compound excels on wet and hard surfaces, while aggressive 6mm lugs provide traction on softer terrain. Extreme conditions call for the XTRM 2. We recommend ordering a 1/2 size up for the best fit.
