Hardwood and tile floors are no problem with Snow and Arrow!  Our special elastic ankle is designed to easily go on and gently hug your little one's ankle, but best of all they are going to stay on wiggly feet!For sizing information, please refer to our size chart in the images. Please note sizes 0-3 months and 3-6 months are crafted WITHOUT leather toe kicks. Sizes 6-12 months and up include leather toe kicks.Snow and Arrow Care: Our slippers are designed primarily for indoor use. Slippers are washable! We recommend a hand wash or to machine wash, simply turn your slippers inside out and machine wash on a cool, gentle cycle.  At the end of the machine wash cycle immediately turn right side out, reshape, and air dry.  Your leather may be slightly stiff but will soften back up quickly with a little wear. All slippers are handcrafted in Rose Bud, Arkansas.
