Hi Merry! @merpreb -- my new SandDuneStepper arrived yesterday and I've given it a few 15 minute trial runs so far this morning for exercise. It's supposed to help with balance as well as being a good massage and exercise for your feet and legs. In theory it's like walking on the beach which I can no longer due since I'm landlocked here in Minnesota. Yeah...we've got some beaches but the sand is just not the same. That's the only thing I miss about my southern California roots. Supposedly it even helps for people with Parkinson's.
