For sale mens Birkenstock Tatacoa , cost around £110, these are marked 43 but they come up big, I take a 9 normally and these are too big so I suggest they would fit someone who normally takes UK 10.  Went for a,walk but realised we're really too big and couldn't return.  As you can see on the soles, hardly any wear. Sorty but i didn't keep the box.  Bargain for someone
