Reebok renewed its endorsement deal with with Sox slugger David Ortiz, and plans to release his new Reebok signature baseball cleat, the Big Papi 2M Mid.

The new cleat will be unveiled at an evening event at Underbar in Boston on Tuesday, April 10th. Ortiz will be joined by teammates including Josh Beckett, Jonathon Papelbon and Wily Mo Pena and celebrity Red Sox fans, including actress Chloe Sevigny, musician Daddy Yankee, Hollywood couple Chris Klein and Ginnifer Goodwin, Super Bowl MVPs Peyton Manning and Deion Branch, premier league soccer star Thierry Henry, former Miss USA and MTV VJ Susie Castillo, top players from the New England Patriots and Boston Bruins and more.

The Big Papi 2M Mid will be available in August at key retailers for a suggested price of $100. The shoe will debut in a special silver/red colorway for All-Star and features Ortiz' profile on the sockliner. In addition, Reebok designers took inspiration from Big Papi's signature precisely trimmed sideburns for the lines on the sides of the cleat.

“Reebok's loyalty and friendship have always made me feel right at home and we are true partners in every sense of the word,” said Ortiz. “I'm happy to continue being a big part of the Reebok family because their gear helps me perform at the top of my game on the field with the style to keep me looking my best off the field, too. Be sure to keep an eye out for me at the All-Star Game where I'll wear my new Big Papi 2M cleat for the first time.”

“Reebok is thrilled to continue our partnership with one of the most iconic names in the sport of baseball — David Ortiz,” said Reebok Vice President of Sports and Entertainment Marketing, Todd Krinsky. “Ortiz fulfills his potential each time he steps up to bat and has the energy and charisma to make him just as exciting off the field as he is on.”

Reebok also endorses players including Jason Giambi, Andy Petitte, Alfonso Soriano, Justin Verlander, and many more as well as fellow Red Sox players Josh Beckett, Curt Schilling, Jonathan Papelbon, Tim Wakefield, Edgar Martinez, Doug Mirabelli, Brandon Moss and Wily Mo Pena.
