Last time I saw heel straps in use was in the late 80s at a site that builds solid fuel rocket motors for military and aerospace uses. They also had testing equipment to check that your shoes really would dissipate any static charge. When you are in a bay with a booster containing 600,000lbs of fuel, static discharges are discouraged.
