Revolutionary Swimrun Shoes The HYDRA ESC is the ultimate swimrun & trail running shoe, designed to work in harmony with aquatic ecosystems. It moves smoothly in the water, provides a firm grip on land, and features excellent water drainage and quick drying.

Ready for any aquatic or terrestrial adventure Swimrun ESC Michelin© Outsole High-visibility Michelin© outsole for superior grip on any terrain. Quick lacing system with a lace pocket to reduce water resistance. BLOOM® Foam Insole The active Bloom® foam insole is the first sustainable material to replace synthetic resins and petroleum-based EVA foam. This material is made from algae biomass, and excessive algae blooms can negatively impact marine environments. Therefore, by utilizing this algae in footwear, we contribute to environmental purification. Breathable Mesh Excellent breathability, lightweight, and comfortable. Quick Drainage and Drying The mesh structure enables efficient drainage and prevents the entry of sand and debris. Also, the use of non-absorbent materials maintains a light and comfortable fit. Tough Rubber Compound The use of a strong rubber compound provides excellent grip and high abrasion resistance. Vegan* *The main materials used in Vivobarefoot's vegan products are synthetic and not derived from animals. However, we cannot currently guarantee complete transparency regarding whether the manufacturing processes of small components such as adhesives and dyes used in the products meet the strictest vegan standards. Therefore, while we believe these shoes are vegan, we are not yet at a stage where we can definitively state this. We want to be honest about this point.
