ProStretch Wooden (Double) - Original Calf Stretcher and Foot Rocker (25% Larger Size) for Pain Caused by Plantar Fasciitis, Achilles Tendonitis and Tight Calves (Non-slip Bottom)

I bought this to work on gaining calf and achilles flexibility. I had a single-foot, blue plastic version and thought I'd move up try this wooden double. It may just be my own anatomy/physiology, but I've found that I don't get as good a stretch with the double as I do with the two singles (I've since bought a second blue plastic one, and use them in tandem), or with just one single for that matter. If you have chronically tight calves/achilles, start with the plastic version made for one foot and go from thereMedi-Dyne ProStretch Unilateral Stretching System It also costs about a third of what the wooden double costs.
