The BUBBLE line features a three-component sole with an antistatic TPU outsole, offering ESD (electrostatic discharge) properties, and a translucent TPU shell with a patented PLUG-IN mechanism. The design allows for the insertion of a cushioning pad made from BUBBLE material within the shell. This material is characterized by thermoplastic elastomeric spheres with high energy return embedded in an absorbent polymer matrix. The system is engineered to provide maximum synergy between the sole components and the BUBBLE cushioning pad, which is made by dispersing functionalized thermoplastic charges in spherical form within a polymeric matrix. The two elements in the cushioning pad work synergistically to protect the user from excessive energy return (rebound effect), thereby avoiding discomfort and strain on tendons and the spine.
