Welcome to Runnin’ Wild Kids!
Founded in 2012 by Stacey and Anthony in Cobble Hill, Brooklyn, we aimed to create a special kids’ shoe store with a true sit-and-fit experience.
In 2014, we expanded by acquiring and renaming a local toy store to Runnin’ Wild Toys, becoming neighborhood favorites.
During COVID, we merged our passions to become Runnin’ Wild Kids, offering quality footwear and delightful toys. We’re dedicated to personalized service, helping each child find their perfect fit while sparking their imagination. Thank you for being part of our journey!
As a small business, we pride ourselves on personalized service, unique products, and a genuine connection with our customers. By supporting us, you’re helping a local business thrive while receiving top-quality care and attention. Thank you for choosing us!
