I used this item a few times after purchasing it. I've included the product description below. I'm selling it because the size was too small for me. Size: 24.5cm SP BLADE 9 The SP BLADE™ 9 track and field spike shoe features mesh panels and a seamless design that moves naturally with the foot, providing excellent flexibility and stability. Suitable for 100m-400m sprints/hurdles, this shoe incorporates FLYTEFOAM™ technology in the midsole for cushioning, and DYNAWRAP™ technology in the lacing system and an ankle strap for stability.
