Well over a year ago I sprayed the inside of my boot liners (cold weather thin soles). To date I wear the boot liner every evening around the house, as slippers. I have the one ankle that gets cold and stars to hurt (left one). Went for tests on circulation and both legs are fine and the left one that gives me a problem is actually a little bit better on circulation. Well the liners stop my feet from hurting, I usually wear them to bed also. Well to date there is no smell from the boot liners. Bob
