It's 22.0cm. It's an item for sale because my child has outgrown it. The pins were too long for elementary school students, so I disposed of them. If you intend to use them, please purchase pins separately. I will ship without the box. It was used only about 5 times in competitions. 【High Performance】 These asics spike shoes are specifically designed for track and field, combining speed and stability. 【Excellent Grip】 The spiked sole provides excellent grip on the track, improving performance in the starting dash and cornering. 【Comfortable Fit】 Made with lightweight and breathable materials, they maintain comfort even during extended use. - Brand: asics - Model Name: EFFORT - Color: Black/Red - Sole Features: Spiked - Usage: Track and Field Thank you for viewing.
