I rarely wear adidas because I find their shoes are a little too narrow for me.  These were no exception.  However, I was training for the Tough Mudder and needed a cheap trail running shoe to train in and do the event in because I expected to throw them away after the event.  I was pleasantly surprised with these shoes.  They drain very well, were pretty light, pretty well cushioned, and held up to some decent roadwork and trailwork leading up to the event.  In fact, I'm still using them two months after the event.  The only thing I think adidas could have done better would be to find a way to incorporate the speed lace or boa lace system like the Salomons do.  Plus, while they were light, they are not anywhere near as light as the Kinvaras or the more minimal shoes, but then again, this has much more cushion and durability.  For $50.00, you can't go wrong with these.
