What is the difference between smooth and textured foam rollers?

Smooth rollers provide uniform pressure across the entire contact surface, making them gentler and better for beginners or general recovery. Textured rollers with ridges, grids, or knobs mimic the pressure of a massage therapist's fingers and can target specific trigger points more effectively. If you have multiple knots or adhesions, a textured roller will deliver more targeted relief, but it may be too intense for sensitive areas.
