Diadora Mythos Blushield 6 Men's Alloy/Steel Gray/Black Providing plush cushion for long distances, the Diadora Mythos Blushield 6 is perfect for high-mileage runners. Stay cool and dry during your exercise in the engineered air mesh upper. BluShield cushion in the midsole absorbs shock from every step to keep you comfortable. Finish it off with a durable carbon rubber outsole, and you're ready to endure those long distance adventures! Shoe Technology Upper: Two-tone engineered air mesh upper provides excellent breathability, flexibility, and support. Midsole: Blushield® technology combines cushioning and responsiveness by minimizing asymmetrical behavior in feet and maximizing shock absorption. Morpho base is carved following the shape of the foot to provide fluid transitions and inherent stability. Outsole: Duratech 5000 compound in the heel improves durability, blown rubber in the forefoot reduces weight. Sizing Important Sizing Note: The Diadora Mythos Blushield 6 runs a half size larger than normal. We recommend you order a half size down from your normal running shoes. For example, if you usually wear a size 8.5, order a size 8 instead.
