The secret to knitting large socks is to use large yarn:) Using the Opal 8-Fach I only needed to cast on 48 stitches, which made for a very quick knit even though they were Men’s Size 11 socks.

Cast on 48 sts
Cuff 16 rows K1 P1 rib
Leg 48 rows K3 P1 rib
Sherman heel
Instep K3 P1 rib (with 1 extra P st added at the start which is decreased away before beginning the toe)
Sole Stockinette
Standard Toe (decrease every other row, and then every row, Kitchener stitch to close)
