Free Ankle Sock Knitting Pattern: September Ankle Socks

Free Ankle Sock Knitting Pattern: A Summer-Friendly Solution

As the weather warms up, my kids have started asking me for socks that fit comfortably with their sneakers during the summer months. This led me to create a free ankle sock knitting pattern inspired by their favorite September Socks, which they wore nonstop during winter. It’s such a joy to see them loving and wearing handmade socks I’ve crafted just for them. But with the rising temperatures, it was time to design a shorter, ankle-friendly version of those beloved socks.

Choosing the Perfect Yarn for This Free Ankle Sock Knitting Pattern

For this project, I used a skein of KnitPicks Hawthorne (affiliate link) from my stash. My daughter was instantly drawn to its vibrant colors, saying it reminded her of sprinkles on a cake. Personally, I love KnitPicks Hawthorne (affiliate link) because it’s strong and holds up well to the wear and tear of active kids. Although it feels a bit coarse at first, it softens beautifully after washing while maintaining its durability. If you’re planning to make this free ankle sock knitting pattern, I highly recommend KnitPicks Hawthorne (affiliate link) for its strength and color vibrancy.

Adapting the September Socks for a Free Ankle Sock Knitting Pattern

The foot portion of this pattern is identical to the original September Socks. The primary difference lies in the ankle design. I opted for a 1×1 ribbed hem for a snug, comfortable fit around the ankle. To add functionality, I included a short row tab to prevent the back of the socks from rubbing against the ankle when worn with shoes.

For the short rows, I used my favorite technique: a modified wrap-and-turn where I add a yarn over before turning. However, this free ankle sock knitting pattern is flexible—traditional wrap-and-turn or German short rows work just as well. The short row tab is all about practicality, ensuring these socks are as comfortable as they are stylish.

September Ankle Socks are a shorter version of September Socks. My oldest daughter requested knit socks for summer because she loves them so much. I just couldn’t say no.

Short rows are used to make the tab on the ankle. I use a wrap and turn (w&t) method of short rows but you can use any method that works for you, understanding I will use the w&t abbreviation for where the short row should be turned.

Abbreviations

Kitchener stitch:

Place half the stitches on one needle, half the stitches on the other needle, (top and bottom NOT side to side)

Cut yarn (leaving a long yarn tail) and thread through a blunt needle.

Set-up steps: Insert needle purlwise (back to front) through the first st on front needle, leaving the st on the needle. Then insert needle knitwise (front to back) through the first st on the back needle, leaving the st on the needle.

Step 1: Insert needle knitwise through first st on front needle, then slip this st off the needle.

Step 2: Insert needle purlwise through the second st on front needle, leaving the st on the needle.

Step 3: Insert needle purlwise through first st on back needle, then drop this stitch off the needle.

Step 4: Insert needle knitwise through second st on back needle, leaving the st on the needle.

From this point to the end, repeat steps 1-4.

Kitchener stitch can be intimidating, but you get into a rhythm:

Front needle: knitwise drop off, purlwise leave on,

Back needle: purlwise drop off, knitwise leave on,

Repeat!

At the end of the row, there is only 1 stitch left on each needle.

Work steps 1 and 3 once more.

P – purl
sm – slip maker
