"The R300s give the best fit around"

By Ellis Bacon

Of course, you can't heat up carbon fibre and remould it (not yet, anyway. Hey, we could be on to something...), but the R300's upper is infused with a thermo-form plastic that allows the shoe to be heated up and moulded to the shape of your upper-foot, giving the best fit around.

The thermo-form insole also adapts to your foot shape with time. And the carbon sole, too, merits more than a mention: its super-stiff one-piece construction weighs five per cent less than Shimano's former top-of-the-range shoe by integrating the heel cup into the sole.
