I just discovered a fabulous product for die-hard walkers (like me) who need the sunshine especially in the winter. There were a couple days when I was leary of going out due to icy conditions. A fellow walker told me about Yak Trak grips that attach to the bottoms of your boots or runners, and they give you a solid grip, even in packed snow or ice. I paid $20.00 Canadian for them but you American ladies can probably find them for much less. I highly recommend them for winter walking.
