The GRID X is the firmest foam roller in the GRID line, providing enhanced deep-tissue pressure for self-massage enthusiasts and those looking for deep pressure sensations. Like the other rollers in the GRID family, the GRID X features a hollow core design that's more durable than traditional foam rollers, helping it retain its shape after continued use to deliver a consistent feel and optimal performance. The extra-firm EVA foam surface is water-resistant and sweat-resistant, making it easy to clean. It also features our patented GRID pattern that replicates a massage therapist's hands in three unique configurations: flat areas like the palm for addressing large muscles, tubular ridges that knead muscles like the fingers, and dense nodules for applying targeted pressure like fingertips. It's like getting three deep-pressure foam rollers in one. The GRID X is the ideal self-massage tool for addressing ultra-sore muscles and soft tissue tightness and discomfort, helping to increase circulation, improve mobility, and ease the tension of sore muscles in the legs, arms, shoulders, back, and neck.
The GRID X is definitely the firmest roller I've tried, so it's best for deep pressure rather than gentle rolling. The hollow core keeps its shape well even after months of use, and the EVA foam surface wipes clean easily since it resists sweat. I really like the patented GRID pattern, the flat areas, tubular ridges and dense nodules give three different sensations in one roller. It works great on my legs, back and shoulders, and helps ease tightness and soreness after training. Not for beginners, but excellent if you want serious deep-tissue pressure.
