Asics S4+ YOGIRI 27cm New and unused. I am selling these because the size didn't fit. Thank you. This model achieves the four "S" of Speed / Stability / Safety / Sub4. It uses "FF TURBO PLUS," the same material as the METASPEED PARIS SERIES, in the upper layer of the midsole. This shoe features a full-length carbon plate. By widening the ground contact area, it supports stable running. It pursues a balance of responsiveness and stability. In addition, the upper material has been updated to be softer and more comfortable on the foot.
