The Babolat SFX is an all new addition to the Babolat performance tennis shoe line, combining proven Babolat technologies in a slightly wider, more comfort-oriented package. New Ergo Motion dual material midsole equalizes pressure points for outstanding cushioning during the rigors of play. Stitchless tongue/vamp construction for excellent forefoot flex. Impressive, out of the box performance with minimal break-in. Continues the use of Kompressor System cushioning in the heel and use of the excellent OCS outsole made by Michelin to provide enhanced traction without sacrificing durability. Excellent all around choice for the player who places a premium on comfort and a plush ride.
