From 2013 to 2017 I wore the GT-2000 as my main running shoe, ran 700 miles in pairs and then switched to the latest generation. During that time I have changed 7 pairs and all have served me well. I bought my next pair in late 2017 and they blistered me constantly on every run past the 2.5-3.0 mile mark. I gave up on the GT-2000 in frustration, but couldn't find a pair that I liked as much. To give Asics another shot, I bought these shoes about a month ago and have never regretted it. They are comfortable, support my feet and have not caused any blisters so far. While expensive I would say the Asics GT-2000's are value for money and I'm looking forward to my next pair in a few hundred miles.
