Looking for the right size ...
Is it possible to rely on the size in "cm" because each manufacturer seems to convert "UK"/"US"/"European" sizes different... Thanks for your help !
As a guide, when I used to wear normal running shoes, I was a US 11.5. I am a US 12 in Nike Frees.
When I first bought my 230's, I heard that they ran small, so I went for the UK 11's (US 12's), like my frees. THey were too long, so I went half a size down, because I have a broad foot, and they are heaps better, but I really think I could get away with a US 11 next time because they have a lot of stretch and a relatively wide toebox. Basically, I could go for my street size shoe (UK10, US 11) and be happy with these. If you like thick socks and a bit more length, go 1/2 size up from your street shoe size.
Everyones foot is different though - so many people say these run narrow - I reckon they are pretty true to size - and they are awesome! :)
