While the first two options were neutral shoes, the Supernova ST is for runners who need stability during runs. Stabilizing features come in the form of a Torsion System and molded heel counter. But it's not all about stability. Adidas also wanted to focus on responsiveness with this shoe model. Dual-density cushioning on the medial side helps to keep you moving. This is an 11-ounce shoe with an 8mm midsole drop.
