I've got bad feet. No, not nasty feet, bad feet. I've got plantar fasciaitis, thanks for your concern. Because of this, running/jogging causes quite a bit of pain. But with elliptical trainers, I can work at the intensity I want, burn a lot of calories and still be able to walk the next morning. In general, elliptical trainers are non-impact, which is great for your joints. This particular elliptical allows you to adjust the stride length, so you can tailor it to fit your specific needs. If you're gonna get an elliptical, you can't beat the Precor products. Sears is great for buying a pair of Toughskins & a socket set, but not so much for home exercise equipment.
