Frankly, for $50 shoes for a 5 year old, I'd expect no blisters, but apparently I was wrong in that assumption.  Don't get me wrong, these are beautifully made and worth the $50, but they gave my son blisters on the insides of his feet (just inside the big toe knuckle near the arch.)  I bought them a size larger in the hope they will last him 2 years instead of just one, so maybe that's part of the problem, but it still hurts (physically and mentally) when you have to carry a 40lb 5 year old boy through a store because his feet are killing him.  I would buy them again, just in the actual size he wears.
