I held off ordering these fun socks on account of the R (7-11) sizing by STP. Well, I like Pantherella enough that I finally took a chance on a pair and lo and behold, my size 12 E foot fit in these perfectly. I've since bought about a dozen pairs.
Bottom line: UK sizing needs to recalibrated for US or simply say they fit to US 12.
