Bryce Harper's latest signature cleat draws inspiration from futuristic protection, Philadelphia's transit system and the journey that always leads home.

Bryce Harper and Under Armour introduce the Harper 11, the latest evolution of Harper's signature cleat franchise and the next chapter in one of baseball's longest-running athlete partnerships. The Harper 11 "All Lines Lead Home" serves as the debut colorway and first retail launch of Bryce's 11th signature cleat with Under Armour.

Earlier this year, Harper announced the extension of his partnership with Under Armour, continuing a relationship that began in 2011 when he became the face of Under Armour Baseball. In 2015, Harper and Under Armour signed a 10-year extension that was the largest endorsement deal for a baseball player at the time. More than a decade later, the Harper 11 represents the latest milestone in a partnership built on innovation and a shared commitment to the game.

Designed around the idea of futuristic protection for baseball, the Harper 11 draws inspiration from Harper's experience as a catcher, catcher's gear and motorcycle protective equipment. The result is a cleat engineered to deliver lightweight protection, breathability and stability while meeting the demands of today's game.

At the foundation of the Harper 11 is a first-of-its-kind traction plate that is wider than a traditional baseball cleat, delivering enhanced stability, comfort and ground feel. Strategic cutouts allow the plate to move naturally with the athlete's foot, while additional ground contact points help distribute pressure more evenly over time and provide comfort across multiple playing surfaces, including turf.

The upper combines a full knit compression sleeve with breathable TPU mesh construction to create a seamless fit that balances airflow, flexibility and support, while integrated lace storage helps keep laces secure during play.

One of the cleat's defining features is its signature impact cage, which serves as both a performance innovation and distinctive design feature. A molded gel insert provides lightweight impact protection, while the toe-box outline forms both a heart and a baseball field, representing Harper's love for the game and the city he calls home. Directional points throughout the cage symbolize the people who help guide his life, including members of his family.

The debut "All Lines Lead Home" colorway celebrates Philadelphia and the many paths players, fans and visitors take to reach the city. Inspired by SEPTA's rail system and the metallic appearance of Philadelphia's train cars, the design incorporates transit line-inspired pops of color throughout the cleat, with distinct route colors across the left and right shoes representing different Philadelphia train lines. The inclusion of SEPTA graphics on the sockliner and Philadelphia's iconic 215 area code on the Pull Tab further reinforces the connection to the city.

The All Lines Lead Home story extends to Under Armour's Yard Icon cleat through five colorways representing different Philadelphia train lines, accented by chrome details inspired by Philadelphia's transit system and train cars.

During MLB All-Star Week, Under Armour will celebrate the launch of All Lines Lead Home with a fan experience in Philadelphia at 1190 Market Street from July 11–14, bringing the Harper 11's Philadelphia-inspired story to life.
