Adidas Spezial

I bought them here on Andele some time ago - they arrived new and still in the box, but I suspect they are not original (they seem slightly larger than they should be and have blue fabric inside?). I compared all the parameters I could find on Google and according to them - original. They also look as they should on the foot, but somehow that suspicious feeling doesn't go away. 😅
Size indicated as 36 2/3, but I think a small 37 might fit too.
I didn't get along with the color and size, so I'm passing them on for a relatively symbolic fee.
