I purchased these shoes for my 11 month old to help sturdy her with learning to walk. when she first tried them on the soles were so slick she could not stand on the carpet. I was so disappointed and intended on returning them. Instead, it came to me to purchase sole grips from Walmart to stick to the bottom of each shoe. Now she has not problem standing or walking in them at all. These are the best quality walking shoes I have found so far. I'm so glad I didn't have to return them.
