The Bombylius socks are magic looped toe-up and they are identical. You can knit one sock first and then the other one. Or you can knit them two-at-a-time. The sock fit is snug. That way the socks keep their form better and stay in place well.

Size: European 38-39 / US 8 / UK 6

Finished measurements after blocking:
-sock length from toes to heel: 22,5 cm (8,86 in)
-sock width after toes: 8,5 cm (3,35 in)

The pattern tells you how to make the sock wider and/or tighter and/or longer and/or shorter.
