These shoes were exactly what I was looking for.  I got them on sale, so they were only like 50 bucks.  I've climbed in them indoor about 20 times so far, and they are holding up well.  They have not really stretched.  I usually wear a size 8, and ordered down to a size 7.5.  I think I could have been find ordering an 8, but the 7.5 are not unbearably tight.  I just take my heels out when belaying or taking a break, as most climbers do.  Haven't noticed the awful smell.  I usually leave them in car my air out in the 100 degree Texas weather, usually good to kill any wayward bacteria.  Rubber is sticky and the shape is good for all-purpose.
