Better than socks! Love these so much
My son has worn these every day of his life! So easy to put on! Do not fall off. Very soft cotton. His feet do not get too hot or cold. We do not use with socks. They are perfect! I have purchased in every size so far!

Stand on and look so great!
I have several pair of slipper shoes for my babe and these are the first ones I grab every day. They fit great and stay on his feet. You can put them on quickly and get out the door. Not to mention they are so adorable!

Cute shoe that stays on
Very use to booties and shoes coming off of baby; however, the fasten on these prevent this without being too tight. The print is also adorable. Will purchase next size as baby's feet grow.

Expensive but they work
The nice thing about these is the snap. My baby has figured out Velcro but not snaps yet. I think they could cost a little less but they are good for when he is at daycare and we don't after to worry about him taking off his socks.
