They're very cute. I used them a few times outdoors for short periods when my child was just starting to walk. The soles and heels are soft and made of fabric, and I was told they are not meant for outdoor walking (they're originally for indoor use, or mainly for display?). Therefore, please be aware that they may not be suitable for toddlers who are not yet steady on their feet. Please keep this in mind. Size: 18-24 months (Listed as 12.5cm, but this is an estimate)
