Mizuno yellow spike shoes, lightweight and perfect for competition. - Brand: Mizuno - Size: US 8.5 / EU 41 / UK 7.5 / JP 26.5 - Color: Yellow - Type: Spike shoes My son used these a few times when he joined the track and field club a few years ago, but he quit after only 2-3 times. Therefore, they haven't been used much. However, they are a few years old and have been used a few times, so please understand this. I'm not very knowledgeable about track and field shoes, so I may not be able to explain everything perfectly, so please ask if you have any questions. I will check the condition and answer. Thank you for looking.
