Michelin's Fiberlite Technology is a lightweight and flexible solution used in technical soles, inspired by the brand's expertise in tyre manufacturing. It uses a thin fabric integrated into the rubber in the forefoot of the sole, which increases durability and comfort. This keeps the footwear lightweight while providing adequate durability.
