Knitting heels in a sock can be a challenge, especially if not used to doing so. This type of heel has you working a heel flap, then a heel turn and finally a gusset. The heel flap is knit flat back and forth until the height of the heel is sufficient for the person's arch. As most sock patterns it is written for someone with normal arches. Someone with a flat feet would not need as many rows, and someone with really high arches, may need more rows. The heel turn helps move the stitches from going across the back of the heel, to going under the foot. Then the gusset picks up stitches on the side of the heel flap to add to the stitches of the heel turn, and starts working in the round again. The gusset continues as the stitches are decreased back down to the original number of stitches for the sock. If you decide to pick them up again, there are also many tutorials on YouTube for sock construction.
