I am a woman with wide feet and medium toes who wears size 8 women's shoes and mostly size 39 Vibrams. I've researched and researched and read a bunch of women's reviews of this show where women had to go taller despite being a man's shoe (and therefore supposedly taller). I ordered men's size 40 (40! when I'm usually 39!) and they fit PERFECTLY. Don't be afraid to size up, no matter how counterintuitive it might seem for a men's size to be larger than your usual women's size. I thought I misunderstood the chart - for example wouldn't a female 39 be the same as a male 37? But I tried the 40's and they fit perfectly. Please note that eBay will only show you the EU size once the shoes are in your shopping cart. You choose a US size and think you're done...then you look in your cart and you see the EU size, and it might be half a size larger or smaller than you expected. Follow this one too!
