The R3 Orthopedic Foot Roller is the result of a year of design work with therapists and elite athletes to create a single small roller perfect for maintenance work and injury recovery for your feet! The contours of the R3 are dig deep into the plantar fascia, the muscles in the feet, and the heel, giving you just the right amount of targeted compression and massage while rolling. The grooves in the roller are also great for rolling out the lateral side of your foot, making the R3 the perfect all-in-one foot massage roller! The surface material on the roller grips well even on hardwood floors, allowing you to get a stable, deep massage no matter where you are, and the unit is small enough to make it travel-friendly. If you've been suffering from plantar fasciitis, heel pain, or tight or sore feet, or you just want to make sure you're doing your maintenance work consistently, give it a try!
