You know what myself and Joe wear mate,
1. What shoes do you wear when riding?
Salomon Speedcross 2
2. How long would you say they last?
They still look pretty damn solid after 6 months or so of abuse, can see them lasting a year.
3. Whats the ankle support like/is there any?
Not a massive amount (but i'm not having any issues with them so they can't be too bad), lots of support for your heel, arch etc, almost like a running shoe/climbing shoe mix
4. Soles: grippy or not that grippy?
Awesome on anything, stratodabs at comps are not at issue!
