This is a mis-matched pair. If you wear two different sizes and they happen to be L43 and R42, these Birkenstock Mayari Habana brown suede sandals are for you. Size 43 in brown suede is not even available for sale in the U.S. It was a gift brought back from Europe, where size 43 Mayari style sandals are available in more colors and materials. I need size 43 for my larger right foot. Right now the only colors available in size 43 in the U.S. are mocca, sand, and black, and only in Birko-flor, not leather or suede.
