User rated ★★★(ok feet)
@OhOk6- I worked in a women's specialty shoe shop for several years, just like Al Bundy. I know all about it, including all the ones wanting me to squeeze their size 10 feet into the size 7 they swore they wear! I know about size variances from style to style, brand to brand, and country to country.
*In person* I can look at a woman's barefoot and never miss by more than ½ size. But as I tried very hard to tell @warpedmind here many times (who threw out SWAGs then insisted he was right, despite any facts to the contrary), it's damn near impossible to accurately *guess* from a bunch of online photos, without forensics software. He was just so adamant about it that @Pinchy and I have an occasional chuckle at his expense because we both got into these situations with him where she's wearing a size 6 shoe in a few pics and says that's her size in an interview, but he's *sure* she must be at least an 8½... from his armchair and laptop. So, @Pinchy's comment was entirely sarcastic.
We do the best we can from other websites, interviews, eBay sales, etc. or one that estimates sizes based on the proportions of DaVinci's Vitruvian Man.
Best example of too small shoes? Have to be Kate Beckinsale. Both her shoe size and toe shape usually leave her hanging off the edge dragging the pavement!
