And then you pull it onto your foot and not only does it mold itself perfectly around your heel (provided you did it correctly) but the front half of the sock now curves itself over the upper part of the arch of your foot (as opposed to stretching itself over). Definitely magic!
One of the major differences between a buy-in-a-store machine-made sock and a handknitted one is that the machine-made sock can be laid out perfectly flat and a handknitted one usually can't (the exception being those that are handknitted with a short-row heel, which is the same and only type of heel that a machine can make). Now look at the definitely-not-two-dimensional shape of your foot and consider which type of sock is most likely to be the better fit.
