Giro's Riela Shoes are perfect for mountain biking with their supportive synthetic uppers and injected-nylon soles that provide stiffness for pedaling efficiency and enough flexibility for walking, too. These shoes also feature supportive EVA-padded footbeds with Giro's Aegis antimicrobial treatment for additional comfort and protection. And for a great fit and feel, there are three hook-and-loop straps, padded heels, and split tongues. There are also reinforced toes and scuff guards for durability, aggressive treads for excellent walking traction, and holes for toe spikes.
