Light weight socks good over or under leggings

Light weight socks good over or under leggings.

These socks are stretchy enough to fit my wide fit, and fit nicely over my leggings with mysneakers for leg day. However, the only reason I didn't rate it a 5 is that it's a little too thin for my liking. I didn't feel like it was going to wick moisture at all, which is important to me while working out.
