These shoes look great, are very light, flexible and breathable.  My 4.5 year old son asks to wear them while he is indifferent to other shoes.  He says these shoes are very comfortable.  I like that after wearing New Balance KT20 Minimus shoes for quite a while his socks did not get sweaty like they do when he wears his Converse shoes.  I purchased the first pair as a Gold Box deal and I will be getting a larger size as soon as I can find a good price.

UPDATE May-2013:  Bought a second pair. Also in black/silver.  My now 5 year old son loves these shoes.  He picks them over the 'light up' shoes that his grandmother bought for him.  Very light, comfortable , and breathable shoe.
