These are great warm boots for little ones who don't want to be inside even when it's cold out.  My 3 year old won't wear boots or shoes that he can't put on or take off by himself and these are really easy for him.  I found them to run small.  My son just grew into a size 10, most of which have some room for growth, but the 10 in these were too small so we exchanged for an 11.
