All other Sperrys are true to size. I've been wearing them for many years. I have over a dozen different styles in my collection all US size 10. I bought these washable suede styles through Walmart Australia and although they are US size 10 they are too small and tight and in fact they are almost US Size 9 and also not a Sperry quality from the past. Shame on Sperry as they now make them in some crappy third world factories with no regard for quality control and proper sizing. Transition to the Sebago brand.
