Employing a traditional Japanese bamboo crafting technique called "yatara", renowned architect Kengo Kuma has turned the Asics Metaride runner into a piece of moving architecture. More than an aesthetic choice, the synthetic strips serve to hold the foot in place, and also form the Asics stripe graphic on the side. The underlying performance knit gives a sock-like feel, and a toggle lacing system secures things further. The dramatic all-white upper sits atop a tan midsole made from eco-friendly Flytefoam cellulose nanofiber, while a white outsole with gel insert at the heel provides traction and bounce. They arrive in select stores and Asics' Japan website on December 20th.
