Baby clothes are notorious for their confusing sizing charts that vary drastically from brand to brand. So when it comes to booties, getting the right fit can easily turn into a nightmare if not done correctly. Most brands strongly suggest measuring your baby’s foot before making your purchase to minimize any chance of a bad fit. A baby’s shoe size also takes into account their age in months, which then corresponds to particular shoe size. Amazon has a helpful sizing guide for all of the booties on our list; just click on ‘’Size Chart’’ located next to the ‘’Select Size’’ icon.
