Boost is the Adidas Adizero Adios 4’s midsole unit. This full-length foam is made up of thousands of thermoplastic polyurethane (TPU) pellets that have been fused together to create a bouncy and shock-resistant piece. It maintains comfort without diminishing in form or weighing down the foot. A thermoplastic skeleton called Torsion System is placed in the midfoot section of the platform. The purpose of this visible add-on is to preserve the structural integrity of the Boost midsole. It also supports the muscles and tendons of the underfoot, making them feel as though they’re buoyed continuously by a sturdy but unobtrusive frame. Open Mesh is used for the upper unit of the Adidas Adizero Adios 4.
