The canvas is thin on these shoes, so it is best not to depend on them for training in walking. A thicker shoe with tougher materials, such as leather, will be needed for beginner walkers just learning how to stand, balance, and take steps. One item is for toddlers and infants and it does not have a sole of rubber. This is a shoe for the crib or inside use. The soles are made of soft terry cloth and cannot be used on outdoor surfaces. Such shoes are for keeping the feet warm and dressing purposes only.
