NIKE ZOOM Lightweight Mesh Upper Gray Running Shoes - Color: Gray - Design: Mesh upper - Sole Material: Rubber sole - Feature: Lightweight - Use: Running AQ2210-200 NIKE ZOOM is an innovative and explosive cushioning system designed for speed and agility. This technology uses compressed air and tightly stretched fibers. After absorbing impact, it quickly returns to its original shape, not only enabling speedy movement but also reducing the burden on muscles, joints, and tendons. Although they have not been worn many times, they have been stored in a closet for a while. I have inspected them and cleaned and brushed them as much as possible before listing them, but please forgive any dirt or mold that may have been overlooked. Returns will not be accepted for any reason, so please purchase after carefully examining the photos. Those who are not familiar with used items, are sensitive, or are slow to provide receipt confirmation are kindly asked to refrain from purchasing. Thank you for looking.
