Adidas Size Guide: Fit & Conversions for Your Favorite Silhouettes

This Adidas size guide brings your favorite silhouettes into one place with exact US, UK, EU, and centimeter conversions. Leather court classics like the Stan Smith, Superstar, Gazelle, and Forum fit true to measurement. Meanwhile, narrow or sculpted lasts like the Samba and Ozweego require going 0.5 step up. Men’s and women’s pairs follow a 1.0-unit US conversion gap.

• Standard-Fit Classics: Stan Smith, Superstar, and Gazelle pairs priced at $100 retail, plus Forum Low ($110) and mesh NMD R1 ($130).
• Half-Step-Up Models: Samba OG priced at $100 retail, Ozweego listed at $120, and Ultraboost at $190 for wide feet.
• Half-Step-Down Models: Primeknit NMD R1 releases priced at $160 retail due to stretchy unlined knit uppers.
• Regional Conversion Rule: UK labels sit 0.5 unit below US men’s numbers and 1.5 units below US women’s numbers.

How Do Men’s and Women’s Measurements Convert Across US, UK, and EU Charts?

Converting between regional footwear labels requires checking heel-to-toe foot length in centimeters (JP). Unlike Nike, which uses a 1.5-unit gap, Three Stripes footwear uses a 1.0-unit US difference on unisex lasts. According to the official Adidas US conversion chart, a men’s US 9.0 equals a women’s US 10.0. That same 27.0 cm measurement corresponds to a UK 8.5 and an EU 42 2/3.

To measure your foot accurately at home, stand on paper with your heel against a wall. Mark the tip of your longest toe in millimeters and check the conversion table below. Following our Yeezy partnership termination report, many buyers returned to heritage court trainers. Wearers moving from 350 V2s back to court models should drop 0.5 unit to their baseline.

How Do Superstar, Stan Smith, and Forum Leather Classics Fit?

Full-grain leather court models including the Superstar, Stan Smith, and Forum match standard foot length. The molded rubber shell-toe cap on the Superstar priced at $100 retail does not stretch lengthwise. Wearers who prefer extra toe room inside the Superstar shell-toe order 0.5 unit up. By contrast, the all-leather Forum Low listed at $110 retail softens across the midfoot after three wears.

The Stan Smith also delivers a consistent baseline fit across standard and decon editions priced from $100 to $120 retail. Originally introduced in 1965 for French tennis player Robert Haillet, the shoe gained a new name in 1978. Brand executives renamed the court model after American champion Stan Smith in 1978. Readers can explore that 1965 to 1978 transition in the Sneakerjagers Stan Smith archive.

Why Do Samba and Gazelle Terrace Trainers Differ in Width?

Casual shoppers often group the Samba and Gazelle together, yet the two terrace icons use distinct lasts. As detailed in our Adidas Samba history and fit guide, the $100 retail indoor trainer features a narrow midfoot. Ordering 0.5 unit up on the Samba prevents pinching along the suede T-toe overlay. Medium and wide feet benefit immediately from that extra forefoot width.

Conversely, the Gazelle priced at $100 retail uses an all-suede upper with a wider forefoot box. That supple suede upper molds comfortably to the foot after a short break-in period. Standard-width buyers order the Gazelle at their normal measurement, while wide-footed wearers go up 0.5 unit. Both terrace models pair flat rubber cupsoles with minimal arch contouring for daily street wear.

How Do Ultraboost, NMD, and Ozweego Runners Fit by Upper Material?

Modern lifestyle and running silhouettes vary in fit depending on upper fabrics and internal cage support. The Ultraboost priced at $190 retail features a Primeknit bootie and a supportive midfoot TPU cage. That knit upper wraps snugly around the arch at your baseline measurement. Wide-footed runners seeking a relaxed feel without removing the insole order the Ultraboost 0.5 unit up.

The NMD R1 requires checking the exact material spec before checkout because upper stretch changes internal volume. Structured mesh NMD pairs listed at $130 retail match standard foot length. By contrast, stretchy Primeknit NMD editions priced at $160 retail run 0.5 unit large. Meanwhile, the chunky Ozweego listed at $120 retail uses thick internal padding that requires going 0.5 unit up.

How Do Exchanges and Platform Fees Affect Secondary Market Costs?

Ordering an improper fit on a final-sale collaborative drop forces buyers to use secondary marketplaces. Because platforms deduct seller fees and charge buyer shipping, an exchange costs 10% to 15% of the sneaker’s price. Checking exact last behavior before entering a draw prevents costly secondary trades. Every major resale platform publishes a tiered commission schedule for athletic footwear.

According to the eBay athletic shoe fee policy, sneakers selling for $150 or more incur an 8% final value fee. Similarly, the GOAT seller commission table deducts a 9.5% base fee plus a 2.9% cash-out charge. Selling a $200 Wales Bonner Samba on GOAT nets roughly $170 after fees, leaving a $30 price spread.

Always check whether an NMD uses mesh or Primeknit before buying: mesh fits true to measurement, while unlined Primeknit requires going 0.5 unit down.

How Do Buyers Target High-Demand Pairs During Limited Releases?

During holiday releases like the Adidas Forum Low Grinch or retro drops like the Air Jordan 7 Cardinal, stock varies by measurement. Men’s US 8.5 through US 11.0 receive the largest factory allocations across retail storefronts. Small women’s pairs and US 12.5+ sell out fastest during online launches. Knowing whether you can wear a 0.5-unit-up alternative doubles your checkout options on launch morning.

Collectors studying our sneaker bot setup guide configure task groups across primary and backup measurements simultaneously. Multi-site checkout platforms including Valor AIO, Cybersole, Stellar AIO, and NikeShoeBot assign specific target ranges across Shopify tasks. Pairing accurate fit selection with residential proxies helps buyers secure personal and collection pairs at retail. Pre-saving your preferred UK and US labels speeds up manual draw entries too.

Is there a 1.0 or 1.5 unit difference between men’s and women’s pairs?

Unisex and heritage Three Stripes lasts use a 1.0-unit conversion gap between US men’s and US women’s labels (for example, a men’s US 8.0 equals a women’s US 9.0, measuring 26.0 cm).

Should I step up 0.5 unit on the Ozweego and Ultraboost?

Yes, the Ozweego runs short in the toe box and requires going 0.5 unit up for most wearers, while wide-footed buyers also go 0.5 unit up on the Ultraboost to accommodate its snug midfoot cage.
