From Vivobarefoot - "Ra III is our stylish barefoot Oxford lace-up shoe made from quality Wild Hide leather, the naturally-scarred leather of free-roaming cattle, sourced from small scale farmers in Ethiopia. Built for easy transition from work to play. Light, flexible, breathable and featuring an ultra-thin sole, this style is the ideal blend of barefoot freedom and smart-casual style." These are brand new with tags and in the box; never worn. They are the wrong size for me and I missed the window to return them to the company. Size 40 EU - check the vivobarefoot site for sizing guidance. 40 EU; 9 US ; 7 UK Tags: minimalist footwear ; Barefoot ; Natural materials ; Leather ; Cork ; Ra 3
