I designed these socks just for myself, I was not planning to release this as a pattern. But someone contacted me and asked for them because she really wanted to knit some of her own.
I designed these on a size M, the stitch pattern would not really work on a smaller or bigger size so for that reason there is only one size available. However if the width of this design suits your foot, you can always knit the foot longer or shorter to work for you.
