FX-S offers a unique blend of high grip, medium-high speed, and maximum spin, thanks to its PRO top sheet and flexible medium sponge. While it's softer than EL-S, it still packs the spin potential of MX-S and the power of MX-P, thanks to a newly engineered rubber surface. The softer sponge in FX-S, combined with its personalized pimple geometry, creates enhanced elasticity, resulting in what’s called "Flexible Spin." Positioned between the hardness of MX-P and MX-S and the softer FX-P, FX-S stands out distinctly from the medium rubbers like EL-P and EL-S, making it a versatile choice for players seeking a balance of spin, speed, and control.
