This pattern is my favourite way of knitting socks. The 2 x 2 rib is nice and stretchy and so comfy. The heel flap and gusset allows for a high arch and therefore a more comfortable fit. I have written the pattern in a number of stitch counts so you can find the pattern that is right for you.

I have also made instructional videos on my YouTube channel of how to make the sock. You can find these videos here:

Part 1: Cast on, cuff and leg

However as a guild if you are using 2.5 mm needles the size you should get (if your gauge is the same as mine), is as follows:

7 inches - 48 stitches
7.5 inches - 56 stitches
8 inches - 60 stitches
8.5 inches - 64 stitches
9 inches - 68 stitches
9.5 inches -72 stitches
