Featuring an innovative design that integrates two separate materials, the Sawtooth Slide Sole creates three unique zones - including the center "sawtooth" zone which includes a blend of two materials for a smoother transition during your slide. The S9 is designed for a long slide with very low resistance, offering slightly less resistance than the S8 but slightly more resistance than the S10.

• One size fits all
