These shoes are amazingly comfortable right out of the box!  I have been wearing them with socks to break them in but have also worn them without for a few hours with no blisters.  I think they run small as I am a 9 1/2 and ended up having to get a size 41 but I LOVE them and every time I wear them I get tons of compliments!  Even the shoe salesman at Nordstroms was crazy for them- he had never seen the red ones and raved over them.  I will definitely buy another pair of these wonderful shoes!
