Positives: thick soles, strong but flexible enough not to impede movement, and anti-slip Inside the shoe is wool, hot attenton barefoot against it by some itches are baby feet but I had bought for the winter and mid season so we are delighted the scratch is still very powerful while slippers are used daily for around 6 months and can adjust the width of the baby's foot they will soon be too small and yet it still looks like new the while my little piece has 2 ½ years and over with crapahutent excellent quality I put 4 stars because the price is high even for slippers!
