After doing a 4-day trip in shoes without a carbon sole, I was tired of the pressure causing me to lose feeling in my toes. These provide a great, firm platform for long days on the pedals. The upper is extremely comfortable and the Boas work well. With the stiff carbon sole they are not great for hike-a-bike, and are much happier staying clipped in. I do like to firm outsole rubber though which is sturdy and will hold up to walking/hiking.
