Belenka barefoot leather professional mens shoes sz EU 46

Belenka makes great barefoot shoes - lightweight and super comfortable. These ones will go with any outfit, including business suits, jeans, etc. I'm the first owner. Bought them for one of my kids, but he never used them (declared he doesn't wear leather) and lost the box somewhere. So these are new and unused, but I don't have the box. I've had them for a couple of years. Please see the pics for measurements.
