The pattern was originally written for Panda Wool. The Panda Silk is a little finer yarn so you might want to knit the sock at a smaller gauge (9 sts/inch) with a US 1 (2.25mm) and use the instructions for a larger size sock.

Pattern designed for the guys in your life but nice enough for the gals too.

Knit cuff down with a heel flap/gusset construction and a wedge toe.
