Aggressive and competitive players won't have to worry about their feet when choosing to boot up with the Propulse Fury. Babolat has identified 9 key pressure points on the foot and uses two technologies to provide maximum comfort to these areas. Active Flexxion and Kompressor technologies provide a high level of cushioning, responsiveness, and support. And as found in the Babolat line of shoes, the Michelin rubber compound of the outsole offers superior durability. Babolat removed some weight out of the outsole, without compromising durability that the Michelin rubber is most known for.
