In which sport are the shoes made entirely of metal?

Shoes made entirely of metal are typically worn in the sport of Track and Field, specifically in the event of javelin throwing. Javelin shoes have metal spikes on the soles to provide traction and stability for the athlete as they run and plant their feet before launching the javelin. The metal spikes help the athlete grip the ground better and generate more power during their throw.

Golf uses metal cleats, Baseball I think as well. Horse racing uses all metal shoes.
