Here are my crocheted baby booties that feature a cuffed top. I did a variation of the original slipper sock pattern by Sharon Klinsky that can be found on several different crochet sites.
There is a wonderful picture tutorial of the original pattern over at Coffee n’Crafts blog site that I found very useful to understand the pattern. Just use a single strand of worst weight yarn for baby booties that will fit a baby up to 6 months old. For a preemie sized newborn, I used a smaller crochet hook and some sport-fingering yarn. If you are wondering, the creme-colored preemie socks shown below have a different stitch look because I turned the toe portion inside out before adding the ribbed heel. By reversing the toe portion, it results in a horizontal stitch look rather than a circular pattern.

Ch 2, work 5 Sc in 2nd ch from hook. Don’t join as the toe section is worked in rounds without joining. Place a stitch marker at the beginning of each round.[…]
