The size is 26cm, and the width is normal. I ran 70-80 kilometers in these after purchasing them, but they didn't fit my wide feet, so I'm putting them up for sale. There's a slight scuff on the heel, but it's not noticeable when running. They are still in good condition and can be used for races and training. Please check the photos. There is some dirt from use, but the color of the fabric makes it more noticeable, so please consider this before purchasing. Please understand that these are used items.
