We’ve challenged the conventional wisdom of expedition-grade footwear, drawing inspiration from native footwear and utilising modern innovation, to thrive in the most unforgiving corners of Earth. The result is the Tundra ESC, a unique barefoot boot that’s been rigorously constructed and tested with wilderness skills expertsfor deep cold exploration, in which you can thrive, not freeze. Live as part of the planet, and not just on it.
Product information
Outdoor Esc Michelin© Outsole
The wild sole for wild adventures.
Vivos are designed with thin soles to help reconnect you with the ground, and provide flexibility for strong, healthy feet.
7mm
Tread depth refers to the thickness of the patterns or “lugs,” on the sole. These are purposefully designed to cater to specific surfaces and conditions, providing an ideal combination of traction, grip, and a sense of connection with the ground.
The Outdoor Esc Michelin© outsole has a 2.5mm base and 7mm lug height, engineered to maximise ground feel and traction. Made from high performance rubber with an aggressive off-trail lug design, this sole gives feet the strong grip, even in the most challenging environments. When you’re climbing hills (or mountains), the articulated toe lugs act like claws, while the essential heel lug provides a critical break for steep descents.
Welcome back the wild.
Human beings aren’t separate to nature, we are nature. When we listen to its rhythm and connect to its intelligence, we thrive. It’s time to get outside and rewild.
