Received my new balance and ran in them the first time yesterday and what a difference from my 560.  No shin splints and had my best time yet on the tread mill.  I'm still shocked these where half off for the standard width.  If you want a larger width you're going to pay almost full price though.  These were well worth $70 and I would pay $100 for them.  These have good cushion and stability as they are wider on the bottom than my 560.  I plan on using these for my police physical test in two weeks.  wish me luck!!
