Open the Knitter's Almanac to page 118, study the pictures, read the pattern, do a diagram of the leg part.
look at the picture of the half finished sock, the wide part is around the calf, the decreasing part is the sides of the heel, the small bit is the top of the foot.
I'd do a diagram if I could figure out a way to draw and post, I can't.
Then measure your leg, or the leg of happy recipient, or some passing stranger.
Length from the back of the knee to the top of your heel, where the Achilles tendon mets the calf, my measurement is 10 inches, err on the side of less this length is easy to add to by adjusting the ribbing. much later

A half finished sock, see the beige cotton between the hands, that's the tentative cast on.
I don't do gauge squares for socks, living dangerously, I use the gauge given on the ball band and use a least one size smaller needles.
Cast on enough st to go up the back of your calf, for these it was 80 st. read EZ's words of wisdom about slipping stitches. Knit 6 rows, 3 slipped st that picked up will be half the 6 st. that are the top of the heel section.
Now you are going to do 2 things. One is increasing to form the sides of the heels, 3 st from the end of the knit row use the increases of your choice and look at the matching decreases, you'll need them. and slip that last stitch, see right in the middle of the picture. The string used for the cast on is just dangling, use it later of the side of the foot.
Just barely viable in the top right of the picture are the short rows to shape the calf, knit 70 st wrap and turn, then 60 st then 50, so you will have 6 more rows at the top of the leg than the bottom.
Knit to 90 st on the needle and decide if you need more short rows, probably unless you have very thin legs and a third sets of additional rows is possible.
Knit to 100 st on the needle and tentative cast on 50 st for the side of the top of the foot. Measure the ball of your foot, and knit 1/3 of that measurement to cover the top of the foot.
Should look something like this.
To the edge of some of these pictures the second sock is visible. I knit this pattern 2 at a time. To help me be sure I will knit 2 socks, and that the socks will be the same. Both important and sometimes difficult
It's not Magic loop just knitting back and forth on a long circular. In theory one could knit these socks on straight needles but I don't recommend it.
If something is unclear leave a comment. I'll be back with the rest of the sock when I get it knit.
