My granddaughter loves these shoes.  Although I bought a half size larger than I would normally - hoping to allow for growth over the coming months - these fit well, with room to grow/wear heavy winter socks and didn't slide around, rub her heels or otherwise cause her discomfort.  There is virtually no arch support but she sometimes wears an orthotic so this probably won't be an issue for her.  In her own words &#34;these are actually very comfortable and fun to run in&#34;.  And that's on the first day of wear.  The suede upper is very nice and even in cold weather these will keep her feet warm.
