Once you go Asics you will never go back. Seriously, I am on my third pair of GT 2000s. They've seen me through hundreds of miles, including my first half marathon last year. I also wear these sneaks for my weekly circuit training class and they are as comfortable in the gym as they are on the road. After purchasing these sneakers I am now Asics loyal.
PS: I have the pink and blue colored sneakers and I think they are much cooler than the black and orchid version ;)
