First, off these shoes are my favorite to run in presently.  I do about 25 miles a week.
They've got a nice neutral feeling, and very little toe spring (something that drives me crazy with other supposedly minimalist shoes).

My only complain is that they fall apart, _FAST_.  The rubber on the bottom of the shoe starts to break down after a few tens of miles.  The toe box developed cracks and wore through within 3 weeks.  Despite the hobo look, I continued to run in them until just recently when the sole wore completely through on the mid-foot.

I estimate they lasted about half as long as the previous generation of the shoe did.  A poor deal for nearly $100.
It seems the trend here is to make the shoe as light as possible, which I don't really think is unnecessary, especially at the expense of durability.

If backpacking gear is any indication, in a generation or two, this design compromise stuff will be sorted out, until then, beware.
