Shimano has launched a limited-edition blue-colored version of its cycling shoe, the R320, which is being worn by a limited number of riders in the Tour de France. The model will also be available for purchase by consumers in limited quantities in Germany, Switzerland, France, Belgium, the Netherlands, Sweden, Denmark, Norway, Finland, Spain, Slovakia, Poland and Israel. Shimano claims to be the market leader in cycling shoes, but declines to give out any numbers. It has been producing them for more than 20 years at its own factories in China and Cambodia.
