From the designer’s notes:

“These are a good in-between weight for wearing around the house and under boots. The ribbed waffle pattern helps the socks stay up quite well, and because of the stretch, they will fit a woman’s medium to a man’s medium foot without trouble.”

There are variations available to change the gauge of the pattern. I’ve made the socks in several different weights from fingering to worsted weight.
