What is the difference between a racing shoe and crew shoe? Actually, there are many differences so let's start from the bottom up. The Sole needs to have larger channels/grips for all weather and all surface grip. Also the material needs to be pliable for being on your knees during a lightning fast tire change, but also have the flexibility needed for all day comfort. The sides need to be flexible, but rugged enough to make it through many seasons. Some of our crew shoes also feature lace guards, Nomex, SFI 3.3/5 certification and, of course,have the full width frontal toe guard.
