Query: Sizing Sucks

Nice sandal. But buyer be aware. These run ridiculously small. I'm on the small size of a 10 and couldn't even get my foot into the sandal. Took a size 11-1/2 for a decent fit. Before you buy try a pair on at a local merchant for correct sizing. Amazon's prices are low for this product but these Keen's run at least one size smaller than labeled.
