Other than a warm winter boot, the one thing I really wanted was a boot that was easy for my toddler to slip on.  These boots are not only warm, but my daughter need zero help slipping her foot in.  I just make sure the shoes are set up correctly next to each other and she sticks her feet in.  Easy Peasy!  We also really like the color, the shoes fit well, and we haven't had ay issues with the shoes accidentally coming off.  I don't know how sizing typically works, but we ordered a c11 based on the size chart, and it's possible we may have sized up a little since they're a winter boot.  My daughter usually wears a 9 in Natives and between a 9 and 10 in other shoes.
