Comments about adidas Men's Response Boost TechFit Running Shoes:

I reconmend this shoe for almost anyone. I think it is just a matter of time before this shoe and the whole adidas boost technology catches on. The boost (the white stuff on the bottom that replaces the previous EVA of traditional shoes) is fantastic to run with. It's this new technology Adidas has been working on for the last 5 years. Maybe a bit snug in the toebox but I have a wide foot and most running shoes aren't kind to me anyways.
