Materials Analysis
The inner lining shows the characteristic ribbed textile used in the Gel-Kayano 30 series designed for premium heel lockdown. The material shows no signs of premature pilling or thinning commonly seen in low-quality replicas.
Stitching Analysis
Visible stitching near the collar area is clean and tight. There are no frayed edges or overlapping threads where the collar meets the inner lining, indicating high standards of manufacturing.
Sole Analysis
Sole is not directly visible in this image focus. However, the internal heel counter structure appears sturdy and properly shaped behind the lining.
Logo & Branding Analysis
External logos are not visible in this specific macro shot of the internal tag. The ASICS logo on the tag itself uses the correct 'A' font and spacing.
Tag & Label Analysis
The tag is the primary evidence here. The 'MADE IN VIETNAM' text is correctly aligned. The date code 'F130823' matches the release timeline of the Kayano 30. The fonts for 'CM', 'EURO', and 'US' are weighted correctly with sharp printing quality.
Box Analysis
Box not visible in image.
Construction Quality
High. The heat-pressing of the size tag is uniform with no air bubbles or lifting at the edges. The transition between the upper and the lining is seamless.
Shape & Silhouette
The heel collar maintains a consistent, ergonomic curve consistent with ASICS performance running silhouettes. Common fakes often have a more vertical or collapsed heel shape.
Color Accuracy
The light blue/grey lining matches the color palette for the 1012B510-401 or similar variants produced in the 2023 season.
Red Flags
No significant red flags identified.
Positive Indicators
Correct style code (1012B510) for women's Kayano 30; precise font kerning on the size tag; correct manufacturing date format; high-quality internal lining fabric.
Key Details

Care Recommendations
To maintain the integrity of the Gel cushioning and foam, avoid machine washing. Use a soft brush with mild soap for the mesh and lining. Air dry only, away from direct heat sources to prevent the adhesives from weakening.
