Tatami sandals. Tatami Is a sister company of Birkenstock. These are three strap sandals with a fourth strap at the ankle. Made of Birko-Flor vegan leather. Birko-Flor Is Birkenstocks proprietary durable faux vegan leather. Men’s size EU 44 US 11. Small nick at top strap to the material as photographed. Structural integrity is still intact, and priced accordingly, since I consider this a significant flaw. No box, in fair to good condition. Marks to material adds a cool distressed vibe to the faux leather which I love!
