Swim and run wild
Built for amphibious adventure
The Hydra ESC is for wild runners, swimmers, and swimrunners seeking a deep connection with the aquatic biome. It?s part of our Ecological Survival Collection.
The materials drain and dry rapidly and stay light when wet. Hydrodynamic, quick-lock lacing allows easy on-the-move adjustments. A RISE foam insole, made with excess algae biomass choking up waterways, glides through water. And the Michelin? ESC sole grips even the slickest, most technical trails. Pinnacle swimrun footwear, pinnacle trail-running footwear.
Off-trail extreme: Extreme traction for extreme terrains, still with plenty of barefoot feeling to connect to nature.
Multi-terrain: Giving you grip and ground feel on everything from wet and dry, rocky and firm terrain.
Fit, Feel, Flex: For natural stability, natural sensory feedback and natural strength.
Our Size Guide is here to help! Vivobarefoot fit 'big' deliberately – we call this ‘the rule of thumb’. Your toes need wiggle room! This is especially important for running. If you can fit your thumb in-between the end of your toe and the front of the shoe, you’ve more than likely found your ideal size.
**After some time with Vivobarefoot shoes, your shoe size may need to increase, as your toes splay out more naturally.**
