Probably the 4th pair of Oakley SI Assault boots/shoes I've owned.  Great blend of performance and looks.  No break in period, just put 'em on and go.

Update 01/04/2013... after only a few weeks of wear the sides of the soles started coming apart from the shoe.  Pretty disappointing.  I epoxyed them back on but not what I've come to expect from Oakley.  Took away 1 star for that.
