I am selling a pair of shoes purchased for my child in October 2025. They were only used for about 3km because they didn't fit well. The soles show no wear and are in excellent condition. I chose these shoes to enhance heel-strike stability, and apparently, the shoes themselves performed very well. They also provided strong rebound, making it easier to move forward even when the legs started to feel heavy. ※Photos from the 4th image onward were taken in natural light. ※I will generally ship within 24 hours. 【Product Description (from the manufacturer)】 One pair for both training and races! World Athletics-approved shoes with a sole thickness of 20mm or less. This model can be used in track races of 800m or more even after November 2024. Mizuno's unique sole shape supports efficient footwork, assisting speed running on both tracks and roads. Thank you for looking.
