Merging Japanese heritage and contemporary style, the ASICS Gel-Kayano 5 OG 'Birch' expanded its predecessor's legacy with the February 2019 release of the retro-styled sneaker. The runner features a mesh upper reinforced with smooth overlays. Underfoot, ASICS’ trademark GEL technology provides stabilizing cushioning to the foot for natural strides. Below, the sculpted sole is equipped with durable rubber.
