I bought this shoe in 2002 and never worn at all.  Recently  in  mid 2012
I started walking in it and after wearing 4 times the sole separated from the  bottom of the shoe.
I used to like Mizuno's but now they must be made cheaper, will not buy again.

PS have run +10 marathons , so I know running shoes, these are terrible don't buy them.  Mizuno would not make it right at all..
