Asics Heatflat FR7 Track and Field Spikes Unisex HEATFLAT FR 7 With a stable flat heel structure, these spikes are suitable for short and middle distances, hurdles, and jumping events. SPEVAFOAM, which provides excellent resilience, is used throughout the midsole, and SOLYTE, which is lightweight, is used in the heel to reduce landing impact. The mesh area of the upper has been expanded to improve fit and breathability. They were only worn for a short period because the user outgrew them. Spikes are not included. There are some scratches. Please check the photos. (I apologize if there are any overlooked scratches)
