Then you are doing yourself a disservice if you have not at least tried one. What does the brand of bike you own have anything to do with the shoe you wear? The S-Works shoe is the best fitting most comfortable shoe that I and a lot of people have ever tried. The varus wedge built into the shoe is also a huge improvement for most cyclists. Sure you can add a Varus wedge later but at the cost of toe box and fore foot room. My pair of S-Works shoes are going on 5 years now and still look and operate like new. They have been a sound investment and one of the best cycling purchases I have ever made.
