Abstract
Devices with one or more internal flexibility sipes, such as slits, to provide improved flexibility, improved cushioning to absorb shock and/or shear forces, and improved stability. An internal sipe is formed by at least a portion of two opposing internal surfaces that can move relative to each other in a sliding sideways motion. Siped devices can be used in most existing products, including helmets and/or helmet liners.
