A true outdoor explorer, the Hopara easily navigates through any terrain — wet or dry. Designed through the HOKA lens, this shoe will blow other mountain sandals out of the water. The Hopara has a synthetic upper with strategic cutouts for drainage while still providing a secure lockdown. It includes a neoprene collar for flexibility and comfort plus a quick-lace system. Providing a responsive yet cushioned feel thanks to a rubberised EVA midsole, the Hopara also features a rubberised toe cap for protection and a sticky rubber outsole for traction in a variety of conditions. Add in 4mm multidirectional lugs for even more grip and the Hopara is your key to adventure.
