Ordered these for my boyfriend as a Christmas gift in a size 14. I was told by the sales clerk that the larger the size the more true to size. They fit a little snug at first but does break in with wear. I also purchased the UGG cleaning kit that included a brush, conditioner, cleaner & water proofed for only 20.00 something dollars! I recommend these for the guy who has everything but some comfy warm slippers!!!
Got these for my father, he usually wears a 12 in Uggs but we had to return and size up because the leather doesn't give much to slide your foot in. Other than that he loves them!
