I adore the Zutano booties! They faithfully stay on the feet, are adjustable (two sizes determined by snaps at the ankle), they wash up extremely well, they provide more than enough warmth without the need for socks and they come is such beautiful colors, too. We had several pairs for our first child and used them from the age of 3 months until she started walking around 10/11 months. They held their colors well with repeated washing and, quite honestly, looked as good the last day she wore them as they did when they were brand new. We loved them so much we decided to forgo socks altogether for our second child as our first child never wore them again once we discovered these booties. They are pricey, but they are hgh quality and worth the investment.
