Product information
Trail Flow All Terrain outsole
Lightweight grip for fast, all-terrain adventures.
Vivos are designed with thin soles to help reconnect you with the ground, and provide flexibility for strong, healthy feet.
3.5mm
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.
Our lightest, most agile trail outsole yet. Built for fast hiking and trail running across varied terrain, with a new construction that maximises grip, resists abrasion and delivers lasting durability.

No Insole
No insole, bringing you even closer to the ground for a greater barefoot experience.
VEGAN*
*The main materials in all our Vegan* products are synthetic and aren’t derived from animals. We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.
