This is the Vivobarefoot Hydra ESC. I bought these last year and wore them twice, but I haven't had much opportunity to use them, so I'm selling them. Size is 44, color is OBSIDIAN/SAFETY YELLOW. Among Vivobarefoot shoes, this Michelin sole has the best grip, so it can be used not only for trail running and triathlon, but also as wading shoes when fishing, combined with waterproof socks or neoprene socks. Please refer to the photos for the condition. Since these are used items, please refrain from purchasing if you are looking for new or extremely beautiful items. Returns and cancellations are not accepted to prevent swapping. The HYDRA ESC is the ultimate swimrun & trail running shoe, designed to work in harmony with aquatic ecosystems. It moves smoothly in the water, grips firmly on land, and features excellent water drainage and quick drying. This innovative amphibious barefoot shoe was developed in collaboration with elite athletes. ♯Moonlight Gear ♯Yamatomichi ♯Hyperlite mountain gear ♯Hyperlite Mountain Gear ♯hikersdepot ♯Hikers Depot ♯Gossamer gear ♯Gossamer Gear ♯Sixmoon designs ♯Six Moon Designs ♯Moonlightgear ♯Locusgear ♯Locus Gear ♯Zpacks♯Cumulus ♯Granite Gear ♯Trail Bum ♯Teton Bros.
