These are shoes I tried on and purchased in-store a month ago. They are 26.5cm. I bought them for the actual race of next year's half marathon. I'm a beginner runner, and I bought the same size as my everyday sneakers. I'm selling these to buy a new pair at 27cm. There is no box or receipt. I haven't worn them outside, but I did try them on in the store. I'm not considering lowering the price immediately after listing them.
