Some people have already testknitted the pattern and I have made some adjustments.
Round 17 should be 56 in stead of 52 stitches.

You can make the socks in any size if you want to.
The size are a direction of shoe sizes.
I made them for Women(W) sizes:
US 6,5/ EU 37
US 7,5/ EU 39
US 8,5/ EU 42
US 9,5/ EU 44

It seems a big leap between the size and that has everything to do with the lenght of the foot.
Ofcourse you can adjust the width as wel if you like to.
Just add a couple of stitches between the “joints” from the front and the back.
I hope you will enjoy knitting these socks. I know I did and with sport weight yarn a fast knit.
