I am in need of a new pair of shoes. Currently, I own a pair of Roos that I pretty much wear everywhere. I want a pair of shoes that looks casual, but they still must be athletic since I do not own a car and get around on bike or foot. I've been happy with this pair of Roos (pictured below) which serve my purpose well, and thought about getting another pair of a different style. Do any of you have some specific recommendations? I wear denim 99% of the time and would prefer a darker shoe.
