I once read somewhere (but I don’t remember, where) that you can knit a sock without a heel if knitting a given pattern.
Therefore I tried it. I find the colours of the sock hideous, on the skein I still liked them, but here… ;-(
I won’t knit another sock.
Actually I should have it knitted higher up and it could have done with a cuff, but because I won’t wear it I restricted it to a Sneaker sock.
Anyhow, the thing about the given pattern is right: That’s how the sock looks like: flat ;-)
I began at the ‘cuff’ and at the toes I decremented by rule of thumb so not to get corners.
As for the pattern you alternately knit three, purl three stitches, every row the pattern is shifted one stitch.
The result is a kind of spiral rib-knit that makes the sock so elastic that it fits the foot all around very well.

Therefore I made a kind of pom-pom from wool rests and put my button inside there and although I find the button awful kitschy I quite like the combination ;-))
