I don't think they are childish, have you seen the color of shoes the U.S olympic track and field athletes wear? for crying out loud. please enjoy your colorful boots and strut your stuff silly. Girl power!!!!
Your style is just that yours! Why blend in when you were born to stand out? If you liked them enough to buy them then plainly it's your style. And who wants to go through life lettin others tell you how to dress. Soon you will let everyone tell you who to date, where to eat, what to drive,and where to go to college. Girl put on those boots and rock your style!
