Five years later I have a pair of socks. Ridiculous considering the second one took just over a week to finish. I hadn't planned on knitting it so fast, but I really wanted to know if doing a different toe and heel would make a toe up sock that fitted my foot. The answer is yes, I love Judy's Magic Cast on and love the gusset slip stitch heel which came from Socks from the Toe Up.
