The Hydro Moc all-terrain system is an evolution of the divisive Hydro Moc, taking it out of the water and into varied environments. All of the models use the same design system, defined by a EVA foam cage upper, which is super-resilient and water friendly. This sockless iteration is created with a 80% recycled nylon upper, a midsole made from BLOOM? performance foam made from 10% algae biomass, and an external rear sling that locks in the heel, with a toggle lace closure giving the wearer easy-on easy-off functionality.
