Rating : - Pile on the miles!
I love the Asics Gt 2120 running shoes. Finding the right running shoes for your foot type is by far the most important part of enjoyable running and running injury free. I have tried alot of different shoes through the years and the Asics Gt series are the best I have found. The 2120's can take the pounding of hundreds of miles. I put on 691 miles on my 2110's. I don't see any reason why I won't get long durability from these shoes too.
