KILLER SOFT features a softer sponge, ensuring extended ball impact time for improved control in both passive and aggressive shots. Despite its softness, the rubber maintains speed and offers enhanced dynamics. Designed for players entering the world of KILLER rubbers, it provides better control and remains highly disruptive, generating a low bounce. Optimal compromise is achieved with 1.3mm and 1.5mm sponge thicknesses, balancing attacking possibilities, control, and disruptive effect. Thicker versions (1.9mm, 2.0mm, and MAX) increase speed but may reduce control and disruption. KILLER SOFT is a great introduction to the KILLER rubber series, ensuring a fun playing experience.
