It is important to make sure that the shoes fit perfectly from the beginning itself. Getting a pair that is too tight while hoping that it will break into a comfortable fit over time is not the right way. Cycling shoes use very stiff materials that do not expand over time. While selecting the shoes, allow a little bit of room for your toes so that there is just enough space for you to wiggle them slightly. While you are cycling, you put pressure on the arch of your feet for an extended period of time. Therefore, if your shoes do not offer enough support for the arch, they can cause injuries in the long run.
