Yes it is Toirneach pattern with a few modifications, as my Manly Guys leg is 19" at the calf. I added 2 repeats on the cuff and tapered one out in the taper on the calf and the second in the foot of the sock. all else was per her pattern. As i'm fairly new to knitting, i made a mistale on the cuff with the yarnovers, so I will have to try to recreate it so they both curl the same.
