I was looking for my first mountain bike shoes and they caught my eye. After a quick review of this and a few other models, I decided to try the Sleuths. I couldn't be happier! The rigid outsole and sticky outsole help your feet stay on the pedals when tackling steep descents and big climbs. I don't have to worry about slipping anymore, now I can concentrate on the track in front of me. Great job Adidas!
