adidas X Speedportal Messi "L10NEL M35SI"

The Adidas X Speedportal Messi "L10NEL M35SI" is a celebratory signature boot released by Adidas in February 2023, roughly two months after Lionel Messi and Argentina won the 2022 FIFA World Cup. The boot's name is a stylized, leetspeak-style rendering of "Lionel Messi" that cleverly embeds two of the most important numbers in Messi's career and life at that moment: "10," his iconic shirt number, and "35," his age when he finally won the World Cup. It represents the first Messi signature X Speedportal release of the post-World Cup era and served as a victory-lap boot worn during his continued spell at Paris Saint-Germain in the first half of 2023.

The boot was officially unveiled and released on February 21, 2023, per Footy Headlines and SoccerBible, both of which pinpoint the launch date precisely. However, according to The18, Messi appears to have worn the boots slightly ahead of the public release — he was reportedly seen debuting the design in PSG's UEFA Champions League round-of-16 first leg against Bayern Munich (mid-February 2023), and he scored a dramatic 95th-minute free kick wearing them in PSG's 4-3 Ligue 1 win over Lille on February 19, 2023, two days before the official retail launch. This pattern — top players receiving and wearing signature boots ahead of the general public release — is common practice in the football boot industry. Messi continued wearing the "L10NEL M35SI" through the remainder of the 2022–23 season at PSG (into March and April 2023) before Adidas moved him into newer colorways later that year tied to the X Crazyfast silo and his transfer to Inter Miami.

The boot is built on the Adidas X Speedportal platform — the same speed/agility silo as the "Leyenda" World Cup boot — rather than a new silo. Reported technology and construction details include:

• A soft, durable coated textile upper containing a minimum of 50% recycled content.
• A cushioned midsole designed for high-speed play.
• A chassis engineered for optimal changes of direction.
• Speedframe outsole on the firm-ground (FG) version, and an external heel lock on the turf (TF) version.
• Design language explicitly pulling visual elements from more than a decade of Messi's prior signature boots — SoccerBible notes the boot "takes design elements from Messi's previous signature boots," fusing aspects from "over ten years of design history," while Goal.com specifies inspiration drawn from the f50.6, the Messi F50 Adizero Mirosar10, the Messi15, the F50 Adizero Messi 370, and the Messi16 Spacedust — effectively a visual retrospective of Messi's entire adidas boot career compressed into one silhouette.

The official colorway is Team Solar Orange / Silver Metallic / Core Black — a notably bold, non-traditional look for a Messi boot, built around a vivid orange base with silver and black detailing and light blue accents referenced in some outlets' descriptions. Footy Headlines called it "an atypical colorway compared to his previous releases." The name "L10NEL M35SI" is stylized directly onto the boot's branding, replacing letters with numerals (L-10-NEL M-35-SI) as a visual pun celebrating both his shirt number and his age at the moment he achieved football's ultimate prize.

Adidas designed this release as a direct response to, and celebration of, Messi's World Cup triumph in Qatar. Footy Headlines suggested "the name was probably decided after the successful 2022 World Cup," framing the boots as recognition that Messi — at 35 years old, wearing the number 10 — had just completed the one achievement that had eluded him for his entire career. The18's coverage leaned into this narrative with a light-hearted tone, describing the boots as a celebration of "life in your mid-30s" and noting that "Messi is having a better mid-30s than the rest of us," tying the boot's playful branding to the broader cultural moment of Messi silencing any remaining doubts about his legacy after Qatar. No direct quotes from Messi or Adidas designers specifically about this colorway were found in the sources reviewed.

The most notable moment associated with this boot, per The18's reporting, is Messi's stoppage-time (95th minute) free-kick goal for Paris Saint-Germain in a 4-3 Ligue 1 victory over Lille on February 19, 2023 — a dramatic late winner scored in the boots just before their official public release. Messi also wore the boots (per the same report) in PSG's Champions League round-of-16 tie against Bayern Munich in February 2023, part of PSG's ultimately unsuccessful European campaign that season (PSG were eliminated by Bayern in the last 16). Beyond these specific reported instances, exact match-by-match details of every appearance in the "L10NEL M35SI" through March and April 2023 were not fully documented in the sources found.
