I am an overweight, 40-year-old chef… so I am on my feet eight hours straight [and I take] 20,000 steps a day minimum. Needless to say, by the time I get home I’m in pain. But ever since I bought this, none! I am flipping amazed! Best investment ever!! Totally recommend! I have had sciatica for 10 years. This is the only thing that has fully relieved it.”
