2026-11-06 11:06

The Stone Island x New Balance 574 Legacy 'Dark Green' (U574LGIL) released in June 2024 as one of two colorways in the collaboration. Turn over the insoles and look beneath them, and the comparison extends to material color, surface texture, and stitching. This real vs. fake guide covers six areas: heel outsole and embroidery, tongue embroidery, insole print, insole backing, size label layout, and construction beneath the insole.

How to Spot Fake Stone Island x New Balance 574 Legacy Dark Green Sneakers

1. Heel

Authentic: The heel section of the outsole has a beige-yellow tone. The “new balance” embroidery flows continuously, with smooth transitions between the letters.

Replica: The same outsole section appears black. The embroidered letters are crowded together, leaving less space between them.

2. Tongue Front

Authentic: The Stone Island embroidery has a brighter appearance, with thicker lettering.

Replica: The embroidery looks darker, with thinner letters and more loose, untidy threads.

3. Insole Top

Authentic: The Stone Island graphic is clearly printed and centered, with balanced proportions from top to bottom and side to side.

Replica: The print looks blurry and rough, and the graphic appears uneven from left to right.

4. Insole Back

Authentic: The back of the insole has a light, whitish-gray appearance.

Replica: The back is noticeably darker, with an overall dark-gray tone.

5. Size Label

Authentic: The authentic reference pair displays factory code 22, with the size table on the left divided into five boxes.

Replica: The replica example displays factory code 47 and a four-box size table.

6. Midsole

Authentic: Fine black stitching runs across a smooth-looking base material with a muted, dark finish.

Replica: The stitching uses thicker white thread. The surrounding material looks rougher and noticeably brighter or more reflective.

FAQ

What Photos Do I Need for a Stone Island x New Balance 574 Legacy Legit Check?

Follow the photo guidelines in the LegitApp app or web app, including clear views of both shoes and close-ups of the heel outsole and embroidery, tongue embroidery, size labels, both sides of the insoles, and the internal midsole. Additional photos may be requested during the review.

Do I Need to Remove the Insoles for Authentication?

We recommend removing the insoles to photograph their undersides and the internal midsole. The midsole stitching and base material are important authentication points, and clear photos of these areas help authenticators make a more thorough assessment.

Does Factory Code 22 Prove That My Stone Island 574 Legacy Is Authentic?

No. Factory code 22 appears on the authentic reference pair, but the code alone does not establish authenticity. Review it alongside the size-table layout, embroidery, insole details, internal construction and other details.
