Diadora R&D labs have developed a technology able to maximise the shoe cushioning effect while ensuring high protection, versatility and dynamic performances. Mass Damper is indeed a sole revolutionary technology design that guarantees maximum comfort and top quality performances over time. The benefits of this technology are clear. This technology extends to cover the whole surface of the sole, allowing the foot to dynamically roll from positioning to take off, without compromising the cushioning. The low-density material of the sole ensures great resilience and compression set performances, for maximum comfort and a high energy return. The thermoplastic polyurethane/ester coating creates an external protection shell that increases the sole resistance to abrasion, tearing, hydrolysis, fuels and oil. Suitable for the most intense activities because it maintains high levels of cushioning, also in static efforts when comfort, support and stability really are essential elements.
