I used these when practicing walking. They were mostly used indoors, but the soles are a little black. From the time they were just starting to walk, I put them on like socks, intending to protect their feet from the cold and the ground. Thanks to these, all three of my children grew up wearing regular shoes without complaint. These shoes were bought for the third child and were only used for one season. Please refer to the photos for the frayed areas. (The manufacturer is not Baby Feet)
