Puma Forever Nitro 2 Thank you for viewing. Size is 27cm. I planned to use these, but I wore them once and ran less than 10km. They don't seem to fit quite right, so I'm selling them. If anyone is interested, please consider purchasing them. I ran outside, so there is some sand on the soles of the shoes. (Please check the images.) I've only worn them once, but please understand that these are used items before purchasing. Thank you.
