Afterthought sock heels

Midweek Masterclass: Afterthought Sock Heels

Afterthought heels can be a little tricky to master, but are perfect for when you need to repair an old sock heel. Learn how to work them in Part Two of this week's Midweek Masterclass.

Afterthought heels

This heel type could be considered the 'Marmite™' heel of the knitting world: you either love it, or you hate it! Champions of this heel style admire its simplicity and the fact you can whip through your socks first, before adding the heels once the main sock knitting is over. Some knitters struggle with the fit of an afterthought heel, but this is nothing a little bit of tweaking can’t fix. 

Afterthought 1

The theory behind this method involves placing a row of waste yarn stitches at the point where you want to insert the heel (5).

Afterthought 2

As usual, you work half the total number of stitches to create the heel. Once the sock is finished, you carefully remove the waste yarn and place all the live stitches onto your needles (6)

Afterthought 3

Next you choose your heel style. Many knitters work the heel in the same way they would work a wedge toe (7), using four paired decreases every second round. When you reach the desired width of your heel you simply graft the live stitches together to finish your sock.

Placing the waste yarn 

To work out where to place your waste yarn for the heel, you need to calculate how long your heel will be. This is fairly simple - you need to know the following numbers: 

• Row gauge (either rows per cm or rows per inch)

• Number of decrease rnds - these figures are provided in the table on the below 

• Length of heel = number of rounds divided by rows per cm / inch 

Once you have this information you know where to place your heel.
Knitting top down: Place the heel yarn once your leg is the desired length. You need to factor in the heel length when measuring the foot for the toe placement. Knitting toe up: Measure your foot. Subtract the heel length from this measurement, this is how long your foot should be. When your knitting is this long, place your heel yarn.

Wedge heel 

Set-up: Pick up all sts from waste yarn - 56 (64:72) sts.
To avoid gaps where the heel meets the leg it helps to pick up four stitches.
Set-up rnd: M1L, K28 (32:36), M1R, pm, M1L, K28 (32:36), M1R. 60 (68:76) sts.
Rnd 1: *K1, SSK, knit to 3 sts before mrk, K2tog, K1; rep from * to end of rnd.
Rnd 2: Knit.
Rep rnds 1 and 2 until 24 sts remain. Graft the heel closed using Kitchener stitch, as you would for a toe. 

If you want to try something a little different, you could knit a star heel (8). It provides an unusual-looking heel that fits surprisingly well. The heel is divided into four equal sections and four stitches are decreased each round.

Star heel

Set-up rnd: *K 14 (16:18), pm; rep from * to end of rnd. You should now have four stitch markers in place.
Round 1: *Knit to 2 sts before mrk, K2tog; rep from * to end of rnd. Four stitches decreased. 

Round 2: Knit.
Rep rnds 1 and 2 until you have the correct number of stitches for your chosen finish. 

This heel can be finished in two ways. 

Option 1: 

Repeat rounds 1 and 2 until you have 24 sts remaining. Graft the live stitches using Kitchener stitch.

Option 2: 

Repeat rounds 1 and 2 until you have 8 sts remaining. Pull the yarn through the remaining stitches to close the heel. 

Tips 

• If you need more room in your heel, try working the heel over 60% of the total number of stitches instead of the standard 50%. 

• You can lengthen the heel by working a few rounds of knitting before you start the decreases.
• For all the mini sock patterns shown in our sock heel series, take a look at Sock Anatomy.
