I purchased these for a toddler who is going through the learning process of potty training and these are absolutely great! I can throw them in the washer or even just hose them off outside and there aren't any issues.  Our daughter was wearing regular tennis shoes while learning to potty train but the shoes started to smell even with frequent washing where as these shoes have essentially drain holes on the sides.  She loves them and I do too!  Also the large piece of velcro is great for securing it snugly around the foot! I would definitely purchase this style again for her.
