I talked about them before. My back usually aches just wearing sneakers. But THESE are wonderful. A nice "bounce" on the pavement is really good for your back. Now that our roads have been paved in the last 1 1/2 years..we have freedom! But the stray dogs don't help.

Also, Dotsie........do you do any activity with your arms at all? I'm trying to swing, twist, bend them to get upper body moving as well.
