Aggressive players can give their feet all the support they need in the Propulse Fury. The Propulse line takes a leap forward and is re-engineered to maximize stability, durability and comfort for the modern player. Babolat identified 9 key pressure points on the foot and uses Active Flexxion technology to provide cushioning, support and responsiveness to all those areas. In addition, the improved Michelin rubber compound is more resilient than ever before, allowing weight to be taken out of the outsole while still providing exceptional durability, even for those that are very hard on their shoes.
