Hi,
I have read people getting 400 + miles on their Nike epic react. Solereview is often a good guide to durability. I tried the supernova several times and when I ran down hills they hurt my ankles, I felt they were to unstable for my 80kg weight. I also got shin splints running with them. Also the horrible plastic cage dug into my mid foot, I found that with the energy boost too. I also have the uncaged ultraboost and find I have similar issues with stability after a few kms. I put a firmer insole which helps a bit. I also have the adidas response 3's - more a walking shoe.
When I tried the solar boost/glide I felt they were more stable - that's why I liked them - I love boost you feel the energy return, but the weight is an issue after running for awhile. I love the Nike epic reacts as I don't have instability issues and I seem to run faster and they seem to help propel me along. They are a bit tight mid foot, but I found a method to stretch them a bit. The saucony triumphs iso 3's are a great daily trainer with everrun so its feels similar to boost just a bit firmer. I didnt like the newer saucony triumph iso 4's - to firm and inflexible, the new saucony triumph iso 5 are coming out soon I here - lets hope :)
The skechers Go run ride 7 are interesting shoe, with the insole, I run slower paces when i take it out they seem a more responsive shoe - quite versatile. You can buy nearly 2 skechers go run ride 7 for 1 Solar boost. I haven't ran in the beacon yet and hope to in the next couple of months. I did try the new Adidas pure go, didn't seem quite stable enough less stable than the solar glide/boost. It would be great if Adidas find a way to knock off 30/40 g.
Cheers
Steve
