I bought these socks in the "Happy Medium" design because I was looking for fun crew socks my daughters and I could share (size 9, 10, and 11 shoes), and these did not disappoint. The "12-pack" might be a little misleading; you'll actually receive 6 colors, with 2 of each color. However, they're a sturdy, basic cotton blend, and we haven't had any problems with the seams tearing or being too scratchy. (One of my girls has sensory issues and usually can't stand socks with toe-seams; these are "cute" enough that she hasn't had any complaints.) The pattern is only on the outside of the sock; if you put them on inside-out you can see the outline. (This works out well for my purposes as sometimes my little angels have a tendency to throw used socks on inside out & pretend they're clean...sharing socks with them is a risk because they're known for trying to wear the same pair until they're crunchy enough to walk themselves to the washer. Shudder. But I digress...) The only minor drawback I've encountered is that they are a snug fit, so sometimes they feel a little tight around the ankles after a long day on my feet (I'm the size 10), so you might not want to wear them on a day when you know you're going to have swollen ankles.
