Hydronaut - Glacial Indifference (reservation)

500 AVAILABLE. ALL RESERVATIONS SHIP IN 2-3 MONTHS OR SOONER. The Hydronaut is our debut release from Hygra. H2prO (literally water) cushioning system from heel to toe - after 4 years of engineering and testing, we've developed the only cushioning in the world that uses pure H2O. Why water? Because your favorite sneaker brand was too scared to try something new.
