There's something similar for those of us who like to walk no matter what the weather. I bought a pair of Yaktrax Pro shoe covers two years ago and haven't gotten a chance to use them yet.
They snap over the bottom of your shoe and present a rubber matrix surrounded by steel coil to the ice, essentially increasing the pressure on each point. The USPS uses these in locations that get a lot of snow and ice and the study says it's eliminated slips and falls.
Just a suggestion as I know broken bones don't heal as fast when one gets older.
[TELECOM Digest Editor's Note: I wonder where I could buy one of those devices for my shoes? Maybe next time I happen to go past Walmart I might (as I sniff and point my nose in the air) walk in the place and look to see if they have them. PAT]
