These shoes have only been worn once on the treadmill for 3 miles. Sizing was just a bit too big for my foot, but overall super comfy. Crafted for distance, the Adapt Runner features a wide toe box and a zero-drop sole for a natural foot position. It includes a removable, textured insole equipped with over 100 nodes that massage your feet and engage your central nervous system with every step. Its breathable knit fabric enhances airflow, ensuring your feet remain cool and comfortable. Mens 6.5/ Woman’s 8
