This project turned out to be a teacher. At the very first look my socks look very disproportional, very long and slim. During knitting I checked many times, but the measurements were correct.
I got very slim feet and ancles, like a child only 16cm.
Thats why 48 st in the round are fine for me and comfy.
But my foot lenght is rather long (I can wear my husbands socks easily). In the picture the socks do not fit in, but fit me in perfection! Yeah!
