Let me start off by saying that I'm not a serious player at all, I just play recreationally. I'm looking for a shoe that will work well on court, but is also comfortable to wear all day, or at least to the gym, for a short jog, etc. I can't justify the cost of a dedicated tennis shoe. So the question is, can a real tennis shoe like an Adidas Barricade be worn as a general purpose athletic shoe, or is that a bad idea? Any better suggestions? Thanks!
