We wanted to add these to our inventory because when I had kids I had a very hard time finding a shoe/slipper for my babies for around the house and to put on them in the fall/winter. 
This is a local Canadian company and will continue to supply them based on demand. 
Sizes range as well as pattern. 
We brought in suede bottoms as your babies are small and crawl. And the rubber bottoms to provide grip as they learn to walk and stand.
