Sent them back.  They were so hard and uncomfortable when I just put them on and you couldn't even walk in them.  It must be phony leather because leather is never stiff and hard like these shoes.  I always get New Balance running shoes that have mesh on them and they fit perfectly immediately and feel so comfortable.  Could never wear these shoes.  Good thing I bought them at Amazon, because they always stand behind all their products and the nice Customer Service lady made it easy for me to return them.
