Okay parents, these KAKU NANU animal slippers are absolutely adorable and perfect for keeping little feet warm around the house! The rainbow color with cute animal designs (they have horses, puppies, rabbits, bears - so many options!) will totally delight your toddlers. Made with cozy warm plush lining and durable rubber soles that provide great traction on hardwood floors and tiles - no more slipping and sliding! The back heel has this smart elastic band that accommodates a wider range of foot sizes, which is awesome since kids' feet seem to grow overnight. The 11-12 US little kid size has a sole length of about 7.7 inches (19.5 cm), and they mark it clearly with XL/11-12 on the sole. The sole thickness is just right - not too thin, not too bulky - and the soft material makes them comfortable for all-day wear. What's really great is they work both indoors and outdoors, so if your little one runs outside quickly, they're still protected. The cute animal designs spark kids' imagination and make them actually want to wear their slippers (win for parents!). Perfect as gifts for birthdays, Christmas, or just because. With over 10 years of experience making kids' shoes, KAKU NANU knows how to make footwear that's both fun and functional. If you're tired of cold little feet running around your house or struggling to find slippers your kids will actually keep on, these animal slippers are definitely the way to go!
