Rukka Rivne Mr is a functional rubber-soled running shoe designed for trails, and it does not slip on uneven terrain. Thanks to the shoe's mesh lining and high-quality insole with a cellular structure, they are breathable, keeping the feet cool and comfortable. Shock absorption is considered in the design process, which is reflected in the material choices such as the Phylon midsole that cushions the impact on the foot with each step.
