Got my Bekket's this morning from Net a porter!! Love them!! You have to go a size up. So I'm a UK 5/ EUR 38. French sizing is a full size up so I took a 39 which fit perfectly.
This is what the personal shoppers told me at NAT and they emailed this shoe size chart to me but they are not doing half sizes. If I took the 38 for sure they would be too tight, there's a slight gap but with thicker socks during winter, I'm good

Funny thing happened-the anthracite came back in stock in 38 after i posted this. I think i will stick to my size since i'm a true US 7.5 and only size up to 38. Ladies it's worth to keep checking!
