Mason Mount | Match-Worn Boots | 2020/21 | Chelsea

Key Significance:

• Nike Phantom GT Elite boots match-worn by Manchester United number 7 and former England international midfielder, Mason Mount.
• Match-worn by the player during the 2020/21 campaign whilst representing Chelsea.
• Fully authenticated and accompanied by the BC Boots UK Certificate of Authenticity, including entry into BC Authenticity Verification™, our online registry for instant verification.

Player Modifications & Personalisation:

• The right boot features “MM19” handwritten internally to the heel area, representing Mount’s initials and Chelsea squad number 19.
• Unlike many of Mount’s boots from other periods of his career, this pair features no external personalised detailing.
• This absence is consistent with Nike’s temporary suspension of athlete personalisation during the COVID-19 pandemic, which ran from approximately March 2020 until June 2021.
• Blank internal size labels further signify their bespoke made-to-measure nature and distinguish the pair from commercially produced retail stock.

Player-Exclusive Construction:

• Fitted with Nike’s SG-Pro soleplate, a configuration not commercially available on the retail Phantom GT Elite model.
• The pair were produced specifically for elite professional use rather than standard retail distribution.
• The combination of blank internal sizing, athlete-specific internal identification, and non-retail SG-Pro construction clearly differentiates the boots from commercially available examples.

COVID-Era Production Significance:

• This pair provide a particularly interesting snapshot of Nike’s elite player footwear production during the COVID-19 period.
• This pair originate from January 2021, during the unusual COVID-era period in which Nike temporarily suspended the application of player identification and personalisation detailing to many sponsored athletes’ boots as part of wider cost-cutting and operational measures, running from March 2020 through until June 2021.
• As a result, the boots present without the external personalised name and flag detailing typically associated with Mount’s player-issued footwear from other periods.
• The handwritten “MM19” internal marking therefore becomes an especially important player-specific identifier within a pair that is otherwise visually anonymous externally.

Collector & Investment Significance:

• A rare match-worn Mason Mount pair from his Chelsea career, originating from one of the most unusual periods in modern professional boot production.
• The combination of COVID-era non-personalised construction, blank internal sizing, handwritten “MM19” identification, and player-exclusive SG-Pro soleplate creates a technically distinctive and historically interesting specification.
• The pair also originate from the 2020/21 campaign, a hugely significant season in Mount’s Chelsea career in which he became one of the club’s most important young players.
• A strong early-career match-worn piece documenting both Mount’s rise at Chelsea and the highly unusual production practices adopted by Nike during the pandemic.
• Fully authenticated and accompanied by the BC Boots UK Certificate of Authenticity, including entry into BC Authenticity Verification™, our online registry for instant verification.
