When To Start Your Fleegle Heel Increases (Where is the “Front of Your Ankle?”)
I happen to be knitting a pair of worsted-weight socks, toe-up of course, and thinking about my lovely knitting students and the problems they run into most often when knitting toe-up socks.
A big one for first-time knitters of my basic Toe-Up Socks for Magic Loop is knowing when to start increasing for the Fleegle heel. Fleegle describes the time to start increasing as "when the knitting reaches the front of your ankle."
I don't know about you, but my ankle has more of a gradual transition than a demarcation where my foot turns into my leg.
To overcome this issue, here's what to do:
Flex your foot as much as you can (above) - this helps the "front of the ankle" become more apparent.
Pull the sock onto your foot (which of course is easy because you're using Magic Loop), and hold it as snug as you'd like it when you're wearing it. If the knitting reaches the crook in your ankle, you're ready to start the Fleegle heel increases.
Here's me trying on my sock - I'm ready to start my heel.
Use both hands to pull the sock on. You can see that my knitting is stretched snug and hits what, over time, I have come to judge as the front of my ankle.
If you're not sure, better start increasing. Most people just learning this technique tend to wait too long to start the heel.

I am excited! I found a site that really helps you learn how to knit toe up socks! thank you! I think I can proceed with my toe up sock knitting.
I did do them on dpns but I have a question. When you work the last row and use fleegle’s no hole do you decrease at the end of the heel/instep needle? Thanks.
Yes. You can download a free pattern to follow along with here: Free Sock Patterns
Just wondering if anyone can explain how to do this heel on DPNs please?
Sure Mags, just put the instep stitches on one DPN and divide the heel stitches over two DPNs. You’ll be working back-and-forth over the two DPNs – you can just pretend like they’re one needle. Just follow the directions in the pattern and don’t even worry about what kind of needles you’re using – it really doesn’t matter. Your stitches can’t tell the difference!
