Vivobarefoot Hydra ESC

The Vivobarefoot Hydra ESC is a high-performance amphibious trainer built for swimrun, wild swimming, and technical trails where wet rock, sand, and mud are all part of the route. It pairs a natural, foot-shaped fit and flexible barefoot feel with confidence-inspiring underfoot protection, so you can move quickly from water to land without carrying extra weight. Fast-draining materials help it dry out between transitions, while the aggressive outsole is designed to stay composed on slick, unpredictable terrain.

Highlights

• Swimrun ESC Michelin outsole uses sticky, durable rubber and multi-directional lugs for control on slippery ground
• Puncture-resistant Pro5 finish adds a protective layer underfoot while keeping trail feedback intact
• Rapid drain-and-dry mesh construction sheds water quickly and helps keep sediment and grit out
• Hydrodynamic quick-lock lacing system with an integrated lace pocket for streamlined, secure adjustments
• Bloom foam insole made with algae biomass helps minimize water absorption and reduces wet weight
• Foot-shaped toe box encourages natural toe splay for balance and stable landings on uneven surfaces
• Recycled synthetic upper materials with an animal-free build for a more conscious, performance-first design
