The original pattern is designed for calf circumference
38-40 cm (14.9-15.7 in) however I have included a slim version of the leg chart that is suitable for calf circumference 36-38 cm (14.2-14.9 in)

Measure your calf from the thickest part while standing.

You can mix and match the leg and foot parts. You can make slim socks in size 38/39 or 40/41, and you can make regular version in size 38/39 or 40/41. You choose.

You are going to need 200-250 meters of both yarn colors each.

The pattern has very detailed colored charts of every step.
