Modern Moccasin Women's size 10

Modern Style Moccasin, Manitobah brand. Brand-new, unused, in box, too small for me, and they don't have a bigger size to exchange, otherwise I would definitely do that. Crafted with top-grade leather for a luxurious, barefoot feel. The classic moccasin construction adds a touch of sophistication to any outfit. They are marked as size 11, but they are too small for 11, they fit size 10. Bought for $135+tax+delivery, selling for just $69.
