SIDI engineers have come out with a new sole for cycling shoes that fit the demands of the endurance riders. The Eleven Carbon/Composite Sole® is incredibly stiff but has a little more controlled flex in the toe. The flex increases blood circulation which helps when asking your body for a constant total effort of a triathlon or a time-trial. The resulting comfort also helps to keep the body motivated to push to the limit and still have the legs for the run.
