adidas F50 Messi "Mirosar10"

The Adidas F50 Messi "Mirosar10" (also listed by retailers as the "Messi 10.1") is a signature boot released in late 2014, built on the F50 adiZero platform but marketed for the first time under a personalized, non-adiZero name tied directly to Lionel Messi's biography. "Mirosar10" is a portmanteau of the Spanish phrase "mi Rosario" ("my Rosario") — a reference to Rosario, Argentina, Messi's home city — combined with the number 10, his shirt number for both Barcelona and Argentina. The boot is widely regarded as one of the most personal and story-rich entries in Adidas's mid-2010s run of Messi-specific releases, and multiple outlets (including Complex) have described it as one of Messi's own favorite boots from this period because of how directly its design connected to his childhood.

The Mirosar10 was unveiled by Adidas in late November 2014, with SoccerBible publishing a launch feature on 24 November 2014 and a detailed "Closer Look" follow-up shortly after; Footy Headlines' initial reveal is dated late October 2014, with the boot going on sale in early December 2014. It was the seventh distinct exclusive Messi boot release of 2014 according to SoccerBible, reflecting how frequently Adidas was cycling through personalized Messi editions that year. Messi debuted the boot on the pitch during Barcelona's 2014–15 season, reportedly scoring in matches including a brace against Córdoba while wearing them, and continued wearing the silo into early 2015 before Adidas transitioned him into the "Pibe de Barr10" edition in March 2015.

The Mirosar10 remained built on the F50 adiZero chassis and Traxion soleplate/outsole associated with that speed-boot line, rather than introducing an entirely new platform — that step would not come until the standalone Messi 15.1 silo in mid-2015. The upper used Adidas's Hybridtouch material (described in different sources as "Hybridtouch" or "Hybridtouch 2.0"), a synthetic leather-style microfiber intended to combine the touch and feel of leather with the water resistance and lightness of synthetic uppers. Reporting also references 3D Dribbletex texturing across the upper for enhanced ball control in wet or dry conditions, and notes that unlike some prior versions the boot dropped Speedfoil paneling in the heel area. The outsole was rendered in dark green to complement the colorway. White three-stripes appeared on the design, and while Adidas had begun moving away from the plain "adiZero" branding convention toward personalized names, some retail listings and SoccerBible's own retrospective piece continued to use "adiZero"-adjacent terminology for the line internally even as the marketing name shifted to Mirosar10.

The dominant colorway was orange with green and white accents — described by various outlets as "Power Teal/White/Solar Orange" or simply an orange-and-green scheme with a lighter textured skyline-style graphic separating the two main colors. The color choice was symbolic rather than arbitrary: the orange represented Newell's Old Boys, the Rosario club where Messi began playing as a boy, while the green represented Rosario Central, Newell's fiercest local rival. According to SoccerBible, the green also specifically referenced a memorable youth match in which a young Messi scored four goals against that rival club in his first significant 11-a-side game. Design details also reportedly drew on local Rosario graffiti/street-art aesthetics for some of the graphic treatment on the upper.

The Mirosar10's defining feature was its insole: a printed map of a specific pitch in Rosario known as the Bat­allón field (the "Batallón" or military-base pitch), an informal, semi-abandoned ground where a young Messi and his friends would sneak through a fence to play unsupervised football. Adidas used this insole detail as the emotional core of the release's marketing, framing the boot as a tribute to the informal, unpolished football culture that shaped Messi before his professional career began. Coverage describes this as marking one of the closest design-to-biography connections Adidas had made in a Messi boot up to that point, with virtually every visual element — colorway, insole map, name — tied to a specific, real detail from his childhood in Rosario rather than to a match, trophy, or generic campaign concept. Sources differ on one biographical detail: some describe the "10" in "Mirosar10" purely as a reference to Messi's shirt number, while at least one source ties it more specifically to it being roughly his tenth season associated with Adidas boots; the shirt-number reading is the more consistently repeated explanation across sources.

Messi wore the Mirosar10 through the back half of the 2014 calendar year and into early 2015, a period in which Barcelona were building toward what would become a treble-winning 2014–15 season under manager Luis Enrique. One retailer/review source notes Messi scoring a brace (two goals) against Córdoba CF while wearing the boot and posting a strong run of form — described as around 15 goals in his opening 16 league matches of that campaign. As with most Messi boot eras of this period, specific goal-by-goal boot identification beyond general retailer/press commentary is difficult to verify with full certainty, and this summary reflects what is explicitly reported rather than inferred.
