On Dec. 5-9, NFL players wore their hearts on their feet for #MyCauseMyCleats.

My Cause My Cleats allows NFL players to express their commitment to the causes that they care about. Some former University of Iowa Hawkeye football players chose to support University of Iowa Stead Family Children's Hospital.

Thank you former Iowa Hawkeye football players

Players will have the opportunity to raise money for their cause by auctioning their cleats off at NFL Auction; 100% of money raised will be donated to the player’s charities. Fans may bid on game-issued player cleats to help players raise funds for their chosen causes.
