If you actually work on them.
In the last 2-3 weeks I will have finished a pair of socks similar to the pair I worked on all summer.
I don't especially like ribbing so I put it off (this time I accidentally did 2x2 instead of 1x1 and I think that helped). I like tall socks to keep my legs warm and dread the long boring leg and put it off. I dread the flap (I double knit so the purl side is a pain in my hand) so I put it off. The only part that goes fast is the gusset to finish.
Who knew if I didn't work so hard at not working on them they could be done so fast.
I think I might be an automatic sock knitter by my next pair. I hardly had to consult a pattern to turn the heel this time.
