Purchased from the official online store, OTTO 958 × Asics Gel-Flexkee Pro. Color: Hunter Green Size: 28cm The following is quoted from the description: The GEL-FLEXKEE 958, a collaboration sneaker between OTTO 958, a joint project of the avant-garde fashion label Kiko Kostadinov and the Los Angeles-based art gallery Moran Moran, is now available. The GEL-FLEXKEE 958 reinterprets the silhouette of the GEL-FLEXKEE, which was developed from motion analysis of skateboarding at the ASICS Institute of Sports Science, and features high functionality, including a split sole in the forefoot. The shoe features the OTTO 958 signature "O" logo embroidered on the tongue flap that covers the laces, and an upper constructed of full synthetic leather and a quilted toe box. I usually wear size 28cm shoes, but I am selling these sneakers because the width was a little tight. Both heels are slightly worn.
