B&Zdesign Baby Boots These are baby boots in the style of UGGs. The boa lining inside is warm, perfect for lots of walks on cold days. I'm sorry, I don't know the exact material. Brand new, never used. Size: 14-14.5cm (Runs small due to the thick boa lining) Height: 16cm Calf circumference: 8cm Color: Gray Outer: Suede-like (I'm not sure if it's synthetic leather or suede, but it doesn't look like cheap synthetic leather) Inner: Boa lining, probably polyester Sole: Well-cushioned, 2cm thick You can remove the rubber band hooked on the side button for easier wear, but it will stretch out. Even without removing it, you should be able to slip them on like rain boots. No returns. Thank you for your consideration.
