The Addaday Oscillator Pro is a new way to roll. Addaday packed a traditional foam roller with oscillating power to soothe tired muscles better than rolling alone. Use it on your feet, calves and legs to shake out this morning’s run and prep for tomorrow’s. Like the Addaday Echo Oscillator, the Oscillator Pro can be used on any muscle group in a static or dynamic position. For an unpowered recovery option, try the classic Addaday Pro Roller.
