I completely understand how mismatched socks became a thing. We were all simply very tired of trying to find the mate. In fact, the only way to guarantee that you will find the mate is to throw one away. It will then show up within three days. It happens like clockwork.
When my niece said these were the shoes she wanted she sent me a link. I really had to look twice. They are not the same. They don’t match. I have never seen these at the school in our little community, so maybe it is just a city thing. Or maybe it is just her friends. Maybe it’s just her?
