I don't have a drawing but what I have in mind is simply a cover that would sit on top of my shoe with a little sewn fabric cup that slips over the front of my shoe to hold it in place sort of like how a rain hood slipes over your head. The back of the cover will have a velcro strap to pull it tight and strap around my ankle or lthe heal of my shoe. The intent is just to block the wind. The tension will keep the toe cup tight and it shouldn't slip off. I'll try to get started on this and I'll post pics when I'm finished.
