"ROLL Recovery® R4: The R4 is a deep tissue body roller designed for runners, cyclists, and active individuals who incorporate foam rolling into their training and recovery routines. Every detail-from the center groove that aligns with your spine to the diamond surface pattern that keeps the roller from slipping-was optimized to target specific muscle groups and deliver consistent pressure where you need it most. Whether you're working through IT-band tightness, calf tension, or back stiffness after high-mileage weeks, the R4 gives you a structured, purposeful recovery tool that feels more intentional than a standard smooth roller.The R4 features a center groove running the length of the roller so you can roll your back without putting direct pressure on your vertebrae. Its shape is designed to address the muscles surrounding the IT-band rather than the band itself, helping you work through lateral tightness more effectively. The diamond texture across the surface improves grip and keeps the roller in contact with your target muscle group during use, so it stays controlled against your body. Internal center support maintains the roller's strength and stiffness, ensuring it holds its shape through repeated use. As an FDA Registered Medical Device, the R4 reflects the level of design rigor and input from elite athletes and physical therapists that went into its development.Why Our Fit Experts Love It""I've used the R4 after long runs and heavy training days-the center groove is genuinely useful for rolling along the spine, and the diamond texture keeps it from sliding around. It holds up well and feels more purposeful than a standard smooth roller."" - Sawyer, Road Runner Sports Fit Expert, Wilmette ILWho It's Best ForThe R4 is best for runners, cyclists, and active individuals who want a recovery tool developed with clinical input and real-world feedback from athletes.
