This sock can easily be made longer in the leg by repeating chart pattern.

I guess I should add that they are done mosaic fashion which means you get the look of something hard to knit when in reality you are only knitting one color at a time for 2 rows and slipping the other color where needed according to the chart. They knit up fast as you’re slipping lots of stitches. If you know how to read a chart and you know how to do stripes, then you CAN knit these socks :o)
