I knit them specifically for these shoes. I would prefer to wear them without socks, but they rub right at the inside of the ball of my foot. So the socks are getting the job done as far a preventing blisters.
It has occurred to me that if I am going to make socks in the future, I need to stick with a solid or semi-solid color. Trying to match up the stripes was just that, trying. And having mismatched stripes? My brain doesn't work that way.
