There are speedskates and hockey skates and figure skates.
They all look different so it's easy to distinguish between them, but the question we wondered was why they're different.
Former Olympic speedskater, Dave Cruikshank, came on Wisconsin Tonight to explain the differences between the blades.
He also shared his thoughts on this year's games and his wife's trip to Sochi. Dave is married to 5-time Olympic gold medalist, Bonnie Blair-Cruikshank.
