Warm toes are important when a person has a leg cast. Crocheting a sock to fit over a leg cast is not difficult. To make it easier for the injured person to put the crocheted sock on, make the sock shorter to fit over the foot part of the cast. Crocheted socks are machine washable and dryable. Once the first crocheted sock is completed, make more in various colors to give the injured person options.

Things You'll Need

  • Scissors

  • Measuring Tape

  • Crochet Hook J

  • Yarn

Step 1

Measure the width of the toe area of the cast with a measuring tape. Take more measurements of the circumference of the cast in the foot area to see how much it tapers upward or increases in size. Take notes of your findings to adjust crochet stitches accordingly.

Step 2

Crochet a chain with a thick chunky type yarn that equals that measurement and then add 3 more chains. A thicker yarn protects toes better. In the fourth chain from hook, work a double crochet. Make a double crochet (dc) in each chain loop back to the beginning of chain. Work 5 double crochets in the end chain loop (for a total of 6 double crochets), then make 1 double crochet in each of the backs of the loops to the first double crochet. Work 5 double crochets in the first chain loop and slip stitch to join. This makes an oval shape. Count the stitches and make sure they are the same throughout the pattern rows. If you need to increase stitches in order to accommodate a more tapered fit, just add a double crochet at the beginning and end of several rounds. Do not turn after any of the rounds. Chain 3.


Step 3

Make a double crochet in the back loop only of the stitch in each stitch around. The piece will automatically make a cupping shape. Slip stitch to join to top of chain 3. Do not turn. Chain 3.

Step 4

Work a double crochet in both loops in each stitch around. Make as many rounds as needed to cover the foot of the cast up to the ankle. Check the fit as you go, remembering that the yarn will stretch, so do not make it too loose.


Step 5

Chain 2 for the last round and work a front post double crochet in the first double crochet of the previous round. Next, work a back post double crochet in the next double crochet of the previous round. Do this all around the round to the original chain two and slip stitch to join in the top of it. This round makes a nice stretchy ribbing effect to prevent slippage. Fasten off. Weave in yarn ends with the crochet hook to hide.
