Ethiopian runner Etenesh Diro finished seventh in her steeplechase semifinal heat on Friday despite running the last 800 meters of the race with only one shoe.
Diro was leading her heat when her right shoe came loose and she collided with other runners. She then attempted to put the shoe back on, but eventually ripped it and her sock off before attempting to chase down the pack.
Diro was able to make up some ground and finished the race in seventh place. She finished with a time of 9:34.70, which was not good enough to advance to the final round.
After the race, Ethiopia filed an appeal on behalf of Diro and she was advanced to the final after review from the Jury of Appeal.
Sara Louise Treacy of Ireland and Aisha Praught of Jamaica also were involved in the collision, and have advanced to the final after appeal.
Diro competed at the 2012 Olympics in London and finished in sixth with a time of 9:19.89.
