Hi KarenMarie,
What a shame to be falling on account of the wrong shoes. I have a similar problem just now--had a fall the other day for no known reason except that the elastic on the slippers I was wearing may have loosened up to the point where the slippers are a wobbly fit. I'm ordering a different type of slippers.
As I was doing that, I came across an article that might be helpful though I'm not sure what you're looking for. Most people want nongrip soles but it sounds as if that's not what you want at all--?
In any case, if you look in the "Gifts for Daily Living" section of this article (in Brain & Life), you might find one of the links useful.
