Fizik's Terra Ergolace X2 combines the comfort of our favorite running shoes with the performance of a mountain bike shoe ready to hit the road. Durable upper and rubberized toe stand up to harsh terrain and the lacing ensures a snug fit without pinch points. For confidence on and off the bike, the Vibram outsole provides good grip on roots and rocks , and the slight flexibility of the sole makes it more comfortable for everyday wear than shoes with carbon soles.
