Thank you for viewing. This is a Birkenstock Reykjavik size 45 [29cm]. The color is the popular Taupe. I also have a black pair, but since this one seems unlikely to be used due to its high durability, I am selling it. New and unused. Purchased at the directly managed store in Grand Front Osaka. Below is the description from the official website: The Reykjavik is a wonderful combination of sturdiness and casualness. It's the perfect pair for a sporty and casual style. Thanks to the polyurethane sole, which takes its inspiration from the Professional series, the grip is outstanding. Even on a long, active day, your feet won't tire thanks to the lightweight Deep Blue Footbed. The upper is made of high-grade soft nubuck leather with a beautiful natural appearance. BIRKENSTOCK's original Deep Blue footbed, shaped to the foot, removable Upper: Nubuck leather Insole: Microfiber Outsole: Polyurethane (PU) Details: Strap with a metal buckle for adjustable fit Footbed "Made in Germany" Color...Gray No stains, tears, or odors.
