The Giro Riela R Womens Shoes are comfortable, supportive and durable to help last a long time and hold up against the rocks and mud while riding. Thanks to a nylon and rubber outsole, durability, grip and traction are improved over the older design. The uppers are composed of a high grade synthetic leather that look great and hold up against abrasion while mountain biking. Three wide straps are found on the uppers to offer precise, simple fit adjustments. The shoes also have a EVA footbed with Aegis anti-microbial treatment. These footbeds enhance comfort and fit while also aiding in transferring power to the pedals for more efficiency.
