Cotton booties are 100%cotton outside and are fleece lined, they have elastic on the inside keeping your little ones from getting them off!!! All booties 9-12 months and larger have non slip on them called ToughTek. It is a rubber waterproof material and they are 100% machine washable! They do run small so I would suggest going up a size!

Sizes for the booties are as follows ( the inches measurements are heal to toe on the outside sole not the inside where the feet go:

3-6m 4” shoes size 2

6-9m 4.5” shoes size 3
