Many years ago, my Grandma gave me these “socks”, they are mostly just to prevent blisters on the toes when wearing dress shoes. To me, they just don’t look comfortable, so I never bothered wearing them.
I’m not sure why I kept them for as long as I did. I might offer them to my cousin, because she likes to flats. In the box they come in, there are five pairs. If she doesn’t want these, then I’ll just send them back to my Grandma, I’m sure she’ll be able to find someone who would like these more than I did.
