To be worthy of adventure, a touring boot must be capable of not just enduring but also excelling in the diverse terrain it will inevitably encounter. Guided by this belief, we set out to develop an entirely new sole for our Unlimited boots–a sole that was as versatile as it was durable. It had to offer exceptional grip to ensure it could withstand hiking in the most treacherous terrain–be that a rocky summit, high-stakes glacial traverse, or a parking lot coated in ice. Yet it also had to interface perfectly with countless binding systems while maximizing safety and control. This led to the creation of a sole that provides the legendary traction and performance of the Michelin Gripwalk system while also featuring DYN inserts. This sole is compatible with both ISO Gripwalk and alpine touring standards. And thanks to its screw-on design, the sole can readily be replaced to maximize the longevity of the boot. No matter how you define adventure–or where you pursue it–you can depend on Nordica’s Unlimited soles.
