This is a fairly simple, but warm pattern for slippers. It uses two strands of yarn OR 1 strand of bulky yarn. I used an N hook for this and I hope I've adjusted the pattern this time to take into account the guage I crochet. These should fit an adult foot. They're warm and comfy too, I made myself a pair!
Toe and foot
With both strands of yarn held together or one strand of bulky chain 4 and join
Rd 1 Ch 3 (counts as 1 dc) 15 dc in ring and join for 16 dc

Repeat row 2 -4 times for small -5 times med and -6 times lg
Rd 1 Ch3, dc in 12 stitches leaving 3 stitches

Turning the slipper inside out use a slip stitch to join the back of the heel. Slip stitch back up to top.
Rd 1 Ch 3 work 6 dc evenly along one side, dc in each of 3 stitches left open when making heel, 6 dc evenly spaced along other side and join (16 stitches)
