These are lightweight and breathable Asics sneakers. The size is 29cm. The opening is also elastic, making them very easy to put on. They've been worn once or twice, so I think they're in good condition. They are a bluish-gray color, and it was difficult to capture the color in the photos, but I think the color in the first photo is the closest. 1021A032 They don't have a box, so they will be shipped in a Nike box. Thank you for your understanding.
