Short-row heels are sleek, efficient, and loved by toe-up sock knitters — but let’s be honest: they can be tricky to get perfect. If you've ever struggled with gaps, loose stitches, or uneven shaping, you're not alone. The good news? These mistakes are common — and fixable!
In this post, we’ll dive deep into 7 common short-row heel mistakes and exactly how you can fix (or prevent) them for beautifully fitting socks every time.
🧶 Quick Refresher: What Are Short-Row Heels?
Short-row heels shape the curve of the heel using partial rows rather than heel flaps and gussets. Instead of knitting across all stitches, you knit fewer stitches in each row, turn, and work back — gradually building the rounded cup of the heel.
Common short-row heel techniques include:
German Short Rows
Wrap & Turn (W&T)
Shadow Wraps
Japanese Short Rows
Yarnover Short Rows
Each method is slightly different, but they all rely on smooth, gap-free turns to look and feel their best.

7 Common Short-Row Heel Mistakes:
1. Gaps at the Turning Points
The Problem: You see small holes where you turned your work — the heel looks loose or "gappy" instead of smooth.
Why It Happens:
Turning too loosely
Incorrectly picking up wraps, doubles, or yarnovers
Skipping a wrap/twin stitch at the pickup point
The Fix:
Pull your yarn snugly when making wraps, doubles, or yarnovers.
Check stitch orientation carefully when knitting two stitches together at the turning points.
Use techniques that are naturally gap-free, like German Short Rows or Shadow Wraps.
Pro Tip: When working German short rows, always make sure the “double stitch” is tight enough that you can't see a gap.
2. Uneven Sides of the Heel
The Problem: One side of the heel looks higher or longer than the other side.
Why It Happens:
You accidentally turned too early or too late.
You missed counting one stitch while turning.
The Fix:
Mark the midpoint (center stitch) of your heel stitches with a removable stitch marker.
Count stitches carefully as you work your short rows.
Some knitters prefer to knit "one extra stitch" past the double stitch or wrap before turning to balance the sides.
Pro Tip: Use stitch markers not just at the midpoint, but 5 stitches from each end to track your turn points easily.
3. Tight, Puckered Heels
The Problem: Your heel feels too tight, puckering inward instead of curving smoothly.
Why It Happens:
Short rows are worked too tightly.
Heel "cup" is too shallow for your foot shape.
The Fix:
Relax your tension slightly when working turning points.
Add a few more short rows (wider heel) by turning farther from the center — for example, leaving 8 stitches unworked instead of 6.
Consider using a short-row method like Japanese Short Rows or Shadow Wraps, which naturally create a deeper curve.
Pro Tip: If you have a high instep, always plan a few more rows to create a deeper heel pocket.
4. Holes on One Side Only
The Problem: You notice that holes consistently appear on the knit side or the purl side, but not both.
Why It Happens:
Inconsistent tension when pulling yarn on knit vs. purl rows.
Incorrect handling of yarnovers or wraps depending on the side.
The Fix:
Be very deliberate about pulling equally snug when making turning stitches on both sides.
When picking up wraps or doubles, always knit through both legs if knitting, and purl through the back loop if purling (depending on method).
Practice mirrored tension: when you turn on knit rows and purl rows, pull the same way.
Pro Tip: Video yourself working short rows to check if you treat your yarn differently when turning on knit vs. purl rows!
5. Visible Ridges Across the Heel
The Problem: You see a clear horizontal line where you turned, even though the gap is closed.
Why It Happens:
Twisting the stitches improperly when knitting them together.
Very tight wraps or doubles that distort fabric tension.
The Fix:
Follow the correct untwisting instructions for your chosen technique.
For German Short Rows: Always knit through both legs as one.
For Wrap & Turn: Pick up the wrap and knit it together with the stitch cleanly, without twisting.
For Shadow Wraps: Knit twin stitches together normally without over-tightening.
Pro Tip: Practice a looser turning motion, and block your socks afterward — light steam blocking can help even out minor ridges.
6. Mismatched Heel Size to Sock
The Problem: Your heel looks great — but the sock either slips off or feels tight around the heel.
Why It Happens:
Heel construction doesn’t match your sock circumference.
Number of stitches worked in the heel isn’t proportioned well to the foot size.
The Fix:
Adjust the starting number of heel stitches based on your foot shape.
If you have a narrow heel: work fewer stitches before turning.
If you have a wider heel: work more stitches before starting the short rows.
Use gusset increases before the heel for better fit (many toe-up patterns recommend this!).
Pro Tip: Toe-up socks with a short-row heel often benefit from 2–4 extra gusset stitches added before you start the heel shaping.
7. Forgetting to Pick Up a Wrap, Double, or Twin
The Problem: You realize too late that you missed picking up a turning stitch — causing a gap or hole after you finish the heel.
Why It Happens:
Losing track of where wraps or doubles were placed.
Working too quickly across heel turns.
The Fix:
Slow down at the center of the heel, when you're working back over the wrapped/double stitches.
Place a small marker one stitch before the turn to alert you to a wrap/twin that needs attention.
If you miss one and only notice afterward, duplicate stitch the gap closed neatly with a scrap of yarn.
Pro Tip: Count your wraps/doubles before finishing the heel — you should have the same number on both sides!
🧦 Final Tips for a Perfect Short-Row Heel
Always mark your halfway point and track your short rows carefully.
Choose a method that fits your style:
German Short Rows for ease and neatness
Shadow Wraps for invisible heels
Japanese Short Rows for clean turns
Don’t be afraid to customize the number of rows to suit your foot shape.
Practice with smooth, light-colored yarn when learning — easier to see stitches.
✨ And remember: Blocking your finished socks often hides tiny imperfections beautifully!
