How to knit a sock with a square heel

In this DROPS video, we show you how to knit a sock with a square heel. The stitches on top of the foot are placed on a thread, while the stitches at the back are kept on the needles and the heel is worked as follows (the heel extends under the foot):

1) The heel is worked back and forth across the heel-stitches to achieve the correct height. For this type of heel, the length reaches midway under the heel.
2) Next, the heel is knitted together beneath the foot.
3) The sock is then continued in the round, with stitches picked up along both sides of the heel length, working towards the toe.
4) This heel creates a square shape, which is why this type of heel is known as a square heel.
