How to Spot an Authentic Asics Football Shirt
ASICS is one of Japan's most established sportswear brands. The company traces its origins to 1949 in Kobe, when founder Kihachiro Onitsuka established the business that would later become ASICS. The brand is best known globally for running footwear, but it has also produced football shirts for clubs and national teams across Japan and Europe for several decades.
For collectors, Asics football shirts occupy an interesting space in the vintage market. They are often less common than equivalent shirts from Adidas, Nike or Umbro, which means authentic examples can be highly collectible while reliable reference material is sometimes harder to find.
The Asics logo
The first thing to examine is the Asics branding itself. Depending on the season and market, the exact logo style may vary but authentic shirts could feature a clean and accurately proportioned ASICS wordmark like on this MVV Maastricht shirt. Depending on the season and market, the exact logo style may vary, but the printing, embroidery or heat application should always appear sharp and professionally executed like on this AS Roma Totti shirt.
Poor-quality embroidery, uneven lettering, incorrect spacing or distorted logo shapes should be treated as warning signs. When authenticating an Asics shirt, it is always worth comparing the logo with official photographs or verified examples from the same season.
The Asics label
Vintage Asics labels vary considerably depending on the production period and intended market. Shirts produced for the Japanese domestic market may include Japanese text, while export versions often feature different sizing formats and manufacturing information. Because of these variations, labels should be evaluated against confirmed shirts from a similar era rather than a single generic example.
The quality of the label itself is important. Authentic labels should display clear printing, consistent fonts and professional stitching. For example, take a look at this authentic AS Roma long sleeve shirt.
Labels that appear unusually cheap, poorly printed or inconsistent with the overall quality of the shirt deserve closer inspection.
The fabric and construction
Asics has long built its reputation on performance sportswear, and authentic football shirts generally reflect a high manufacturing standard. Many vintage examples from the 1980s and 1990s use heavier polyester fabrics than modern football shirts, while later models feature lighter technical materials as football kit technology evolved.
Construction quality should be consistent throughout the garment. Check the stitching around the collar, sleeves, side seams and hem. Loose threads, uneven seams or poor finishing are all reasons to investigate further, particularly if the shirt is claimed to be an original match-era piece.
The product code
Some Asics football shirts include product codes or manufacturing references on their internal labels. These can be useful when available, but they should not be considered a standalone authentication tool. At Secondhalf, we were unable to find reliable documentation of a universal Asics football-shirt coding system covering all eras and markets, which means codes are generally most useful when combined with other checks.
If a product code is present, compare it with verified examples, catalogue images or trusted collector resources whenever possible. As with other modern brands, a matching code can support authenticity, but it should never be considered definitive proof on its own.
Club-specific details
One advantage of authenticating Asics football shirts is that many historical examples are documented through online kit archives and collector communities. Details such as club crests, sponsor logos, manufacturer branding, colours and shirt design should match official examples from the correct season.
Even small differences in sponsor placement, badge shape, collar design or colour tones can warrant further investigation and comparison with verified examples. Whenever possible, compare the shirt directly with official photographs from the season in question.
Rarity and provenance
Provenance becomes increasingly important with less common Asics shirts. Documentation such as original purchase records, photographs, or a well-established ownership history can significantly increase confidence in authenticity.
Because many vintage Asics football shirts appear less frequently on the collectors' market than equivalent shirts from larger football manufacturers, collectors should take extra care when evaluating examples that are difficult to verify.
At Secondhalf Store, we check every Asics shirt individually before listing. If you have questions about a specific piece, get in touch.
