The Magma R Rock is a road cycling shoe designed for winter rides with Primaloft insulation. The NRG Air Carbon Reinforced sole has a rigidity index of 8.0 combined with an overlap construction upper helping to transfer power by reducing the dispersion of energy. The SLW2 dial closure system evenly binds the foot without any pressure points and features step-by-step release, which allows for adjustment of the shoe by the millimetre in a quick and intuitive way. The integrated heel seat with directional fiber inner material helps to prevent the lift of the heel while pedaling, the toe box is sealed to prevent drafts and the exterior is reinforced in TPU material for durability.
