I found this pattern on the Blog Knot Your Nana's Crochet while looking for patterns to make for a baby
The cute shoes are for sizes Newborn and 6-12 months (basically booties for a baby).
She calls the pattern Converse High tops which is a perfect fit for what they look like! There are wonderful step-by-step photos and instructions.
Besides these cute booties take a look at her many other free patterns on the site you will find lots of crochet inspiration and great FREE Patterns.
