hey there! if you want to try a new heel technique i highly recommend the short-row heel. it fits beautifully and is more remniscient of the "commercial" sock, and once you get the hang of it it's really easy to do. they are knit the same way whether you are going from the toe up or the top down.
someone on this site once gave me a link (and i can't remember who, am so sorry!) to the sherman heel short-row method and i loved it - it worked well (photo attached of dad's socks). i also like lucy neatby's garter stitch short row heel method.
sherman heel (i think it was salsa or hilde who sent me this, thank you so so so so much):
here's a pic of my dad's fathers day socks done with the sherman heel.
have fun on your sock quest!!!
