SIZE IS NOT APPROXIMATE!!!!! It is difficult to determine exactly what size these are but I would guess about a US 7. I have some size 9 this style and these were advertised as a EU40 and they are very small for my US 9 foot. The listing was a “size 40” it said: 6.5 US (7 UK, 39 EU) which is all incorrect. So buy at your own risk. The soles are way too worn in to determine even with pencil shading over it with paper. Good, used condition, soles are worn in, bought second hand online and they’re too small for me. Smoke free home, have pets. No returns.
