I'm really pleased with the quality & price of these shoes. Shipping was instant too.
I recommend ordering a size up. Luckily, we've purchased a LOT of tap shoes.. so I know they run small.
My daughter (5 years old) wears a size 11 to a 11.5 (depending on the shoe - on a foot measure thingie at the mall, her second toe, which is longer than her big toe, is right at the 11.5 mark) So, I ordered a 12.5 in these. They fit well and have about a "half of a thumb" between the shoe and her toes, which they recommend. So... now to break them in before dance class!
