The Hydra ESC is our pinnacle swimrun and trail trainer, built to thrive in the aquatic biome in harmony with nature. It?s a pioneering take on amphibious barefootwear, created alongside elite athletes to glide underwater, grip on land, and drain and dry quickly.
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.**
