1. A higher more protective heel, maybe not as high as the AZT 90 II but a lil higher than it is now and maybe a heel counter that protects and holds your foot better.
2. Narrow the cleat down a bit, NOT a lot to the point were it is like the Vapor, or F50, or the Predator but still keep it wide because it is the reason why i bought it. The AZT 90 II had a good with, maybe the same as that.
3. Make it more flexible on the outsole, the additions of the stuctural bars made it really rigid with hardly any flexibility but i got used to it. Maybe they could use the same outsole as the Air Legend they just released.
Those are just some main things I thought could be made better for when they realease the next Air Zoom Total 90. I liked to hear your thoughts because if there are a lot of the same thing I'm sure Nike will take notice.
