So my foot size is usually 5.5, sometimes I can wear a 6 in some brands, if I'm lucky. Women with small feet, you know what I mean here.... socks sized 5 - 9 are not made for us. If they can fit a size 9, they cannot fit a 5. Why do these companies insist on vexing us like this? The cute tiny "no show" socks certainly aren't no-show socks for us. All that extra sock hanging out the back looks like our shoes are about to set sail. So I started trying kids socks. Poor children!! Kids' socks are usually thin.... SO thin. It's kind of like a layer of tissue paper and left me with blisters if I wore them for a long day of walking. Sometimes they didn't stay put because they would ride down. And the seams in kids' sock are egregious. I tried one brand of kids' socks and rogue threads kept wrapping around my toes. Enter this brand of socks right here - they're substantial like adult socks. No crazy seams. No weirdness in how they fit. The only other brand I've found that wears well like this is Spotted Zebra, size 1 - 3. Those are slightly thinner than the Amazon Essentials. I'd consider them perfect for summer shoes... converse and whatnot and they come in super fun colors and designs (so if small footed adult women want sharks and monsters on their socks, by golly, it can happen at less than novelty store prices). I use the Amazon Essentials kids socks for my Doc Martens, etc. and bought size 9 - 2.5. So, for now, I have two brands of socks that will fit me and, sock gods willing, they'll continue to be sold.
