This was my first pair of cross-trainers...ever.  I was looking for a cross training shoe to wear with my jeans and shorts but was built solid enough for the occasional run/workout.  I found these and I have to say that they may be the most comfortable out-of-the-box shoes I've ever worn. There was literally no break-in as my size 11s fit perfect right out the gate. These look good with jeans...but they look really good when I wear them with my casual pants and joggers. I use these at the gym for weight days and I've had no issues getting my cardio in them. I don't think these are the best running shoes...but for cross-fit style workouts, ellipticals, rowing machines, and walking....these are fantastic.  Highly recommended and my pair have been holding up admirably.
