If you have foot drop, you might try something called a "Dorsi-strap".
I use it for walking in the mall, yard work, golf - anytime when I know my foot might get tired or that I might need help with the toe clearance. It was a great help to me this Spring when I was following my grandchildren around Disneyworld, SeaWorld, etc, etc. It is really quite simple - it is inexpensive and it really does help with the foot drop. And, it isn't a big, bulky foot brace!
Hope this helps!
