Sorry I haven't written a pattern. But maybe this helps, if you want to make them:
I chained 2, then worked 6 hdc in 1st chain. I joined and worked in the round until i finished increasing, and then i just worked a spiral of hdc's till i got the length I needed. For the opening, i started working in rows. To shape the heel part, i decreased in the middle of the rows until i had about two stitches left. Then, I just worked in the spiral again for the "cuff".
I hope this makes sense, English is not my mother tongue
