Thank you for viewing. This is a listing for Altra Olympus 4, US size 8.5 (26.5cm). I was interested in Altra and wanted to try them out, so I purchased these used from another site. However, I think the heel is a little worn, and they were too big for my feet (actual size 24.5cm), so I am listing them. They were cleaned when I purchased them, and I wore them 2-3 times. I have thoroughly cleaned them again for this listing. There is wear and tear overall, please check the images. The soles seem to have a lot of life left, so how about these if you are looking to try them out?
