“I have been ordering shoes , and wearing most Gravity Defyer shoes since probably 2016 if not sooner. Yes it was earlier because of a back operation. I mostly wear the Ion, although I shouldn't say that because now they will be sold out LOL. They have made my Arthritic body whole. I truly believe if it was not for G-Defy I would be in a wheel chair. I was a Jazzercise instructor for years and we had to be certified with The National College of sports Medicine and I ran 4 Marathons. ILY G-Defy”
