Siumlation White Sneakers Size 8-1/2

Siumlation, white sneakers. There is no size on these. They fit me and I wear an 8-1/2. There is no material tag. They feel like faux leather to me. These lace up. Gently used. There is a scuff mark as seen in the 6th pic. There is some discoloration on the back on the one heel as seen in the pics.There is some minor dirt on the laces. Smoke free home
