Feel the joy of swimrun adventure. The Hydra ESC brings pinnacle swimrun performance through pioneering design. Hydrodynamic lacing and a Bloom® foam insole help you glide through water. All materials drain and dry quickly and stay light when wet. And the Michelin© ESC sole grips the slickest, most technical trails.

REVOLUTIONARY SWIMRUN FOOTWEAR

• The quick lacing system features a lace pocket for hydrodynamic performance
• The closed-cell Bloom® foam insole, made with EVA and 10% Algae Bloom® (which harms our oceans if not removed), absorbs minimal water to reduce wet weight and increase your water speed
• The materials drain and dry quickly, and stay lightweight even when dripping wet
• For barefoot adventure-seekers who want to get fully immersed in nature and experienced in their journey of barefoot exploration

LOOM® FOAM INSOLE 

The Active Bloom® Foam Insole is made using the first sustainable alternative to synthetic and petrochemical EVA foam, derived from algae biomass. This algae can damage our oceans, so harnessing it in our footwear helps clean up the environment.

PUNCTURE RESISTANT

The Pro5 Puncture Resistant finish is a lightweight and flexible 0.8mm layer on the sole. Protective underfoot to keep painful bits out, but still letting all the feeling in.

ANIMAL-FREE

Made from materials that are free from animal products.
