Pfffft! Fart Factory: your little one might not get the joke, but your friends will! Red PU leather that is 100% vegan using no animal products, and is machine washable. Hand embroidered "pffft!" cloud and "Fart Factory" accents. Double sided elastic z-strap and velcro closure for easy on/off and adjustable width. This fun shoe comes packaged in a collectors tin "Lucky Penny Saving" lunch box - eliminating cardboard waste from a box. Plus, a percentage of all Silly Souls purchases go towards the Feed the Children charity. What a great company to support!
