As far as durability this shoe is awesome. I am at just about 400 miles and the shoes still feel great. It's funny because I have been looking at other shoes at the running store, but really have no reason to get a new shoe, because this shoe still feels great. So I have no complaints in that department.
The support in this shoe I felt was great too. I have run in a lot of stability shoes and this shoe does the job. This shoe is generally sold in the light support category but it seems to work for me. Having run in shoes like the Asics 2000, Brooks Ravena and Nike Structure, I think the Lunar Glide 7 does a great job competing with them in the stability category.
