I currently use Adidas Barricade 7's. They usually last me around 6-7 months. I am wanting to try a lighter shoe and from what I gathered the Adidas Feather 2 is more durable than the Nike Vapors. Is this true? How long will the Feathers 2 last me if I get 6-7 months out of my Barricades? Are there any other lightweight shoes that are durable (for a lightweight shoe)? Thanks!
