I have started with sock C. My row gauge is off, so after the 1st gussett I already have reached my foot lenght. I gather you cannot alter the pattern in sock madness, so not sure how to solve this…

I did the decreases on the 2d gusset every row instead of every other row. The sock still came out too long in the foot = 26cm, unstretched. I need a 22cm finished foot.

I frogged and started the gusset 2 rows after the colorwork band. Fit is much better now!

DD did not like the turquoise. So I knit the 2d sock with more subdued colors. She now has fraternal socks. Not sure if she likes that…
