These socks actually do stay on!!! They are super cute, you can even mix and match them. Costumer service was great. They run pretty true to shoe size, so if you know your little ones shoe size, use the sizing chart link provided. If you go by age alone, the seemed to run a little big for our little one. I am too lazy to take hang dry them, but I dry all my baby stuff on delicate, and they help up fine. My only complaint is that they aren't cotton. The synthetic fibers that they are made of run a little warm, and we live in Houston, so they aren't ideal for all situations.
Bought these for my granddaughter, twelve months old. I bought the 6-12 or 9-12 months...can't remember. She is a small 11 month old, and has very bad eczema. The right size for her would be the 12-18 months. The socks cannot be taken off by my granddaughter...so she can't scratch. This is wonderful. The sizing is off, but the product is otherwise excellent. My daughter wanted to use them for a few days. They are that good!!
I bought these for my granddaughter. They are great, she loves the faces on her feet and it makes her more active grabbing at her toes.
Just as you showed on the shark tank! They are great!
