I wouldn't totally disagree with this. At the end of the day though, most tennis shoes take a lot of abuse, and the good ones are ~ $100 on average.
The Vapor 9s feel so incredible on the feet, and are so supportive for being so light that it is worth it to me. They really are luxury tennis shoes, and as we know many luxury items have their drawbacks in terms of maintenance and other things.
You just have to decide if it is worth it, but I have made the move to light shoes like the Solutions and Vapors and am really happy.
