I found the pattern on All Free Crochet. There’s even a video you can follow.
I’m not sure I like the feel of the stitches wearing them barefoot, but with socks they seem just fine. The hubby is begging me to make him a pair, so I already have something to make him for Christmas this year!
I added some height to the second pair I made so they would keep the ankle warm, too. I’ll try to remember to post them and a modified pattern after I’ve posted some more backlogged projects.
