These are ASICS HYPER RACER running shoes, compatible with 20mm or less. This is a track-compatible model that complies with WA Rule TR5 for 20mm or less. They are like new, only tried on once on the track. The size is 24.5 cm, and the color is red. I am also selling other great items (^o^). Below is the manufacturer's introduction. The HYPER RACER™ is a long-distance racing shoe developed for entry-level athletes aiming to break their personal bests. The flat sole design allows for smooth weight transfer from ground contact to toe-off. The forefoot of the outsole features a design that enhances toe-off and propulsion, providing excellent grip performance during running. Additionally, an E.V.A. insole is used to achieve a flexible fit. ■Materials: Upper/Synthetic fiber, Synthetic resin Outsole/Rubber sole, Synthetic sole (EVA) Type: Running shoes Gender: Women's
