Let me first start by saying that I ONLY BUY REEBOK SNEAKERS! I find SKETCHERS to be of poor quality & New Balance uncomfortable.  Reebok products are amazing and these are no different!  RealFelx are light and have a very small profile, but are surprisingly comfortable.  These are not my main "WORK-OUT" Sneakers, I have some ZIG-ZAGS for that, but these I keep in a spare gym bag in my trunk in-case I want to go to the gym on my lunch break!  Fantastic Product!
