I bought these for my 15 year old son - who happens to have Type 1 Diabetes and flat feet.  It's hard to find a running shoe with good arch support that doesn't rub blisters on his arches.  This shoe is perfect!  From day one they were very comfortable (not stiff as mentioned in other reviews), extremely lightweight and NO BLISTERS! The White/Black/Silver/Slam color is nice (the shoe is light gray, not white) and they run true to size.  This is his first pair of Brooks, but certainly will not be his last.
