A retro athletic silhouette reworked with a concealed height-enhancing structure. The black upper keeps the appearance understated, while hook-and-loop straps introduce a functional detail reminiscent of vintage training shoes. It is a suitable direction for casual footwear collections combining nostalgic sports styling with everyday practicality.

The defining feature is the 6cm internal lift. Unlike an exposed platform, the height-enhancing structure is integrated inside the shoe to preserve a more conventional sneaker profile. Breathable mesh adds visual lightness, while the soft sole provides flexibility for daily movement. The adjustable straps also allow the instep fit to be refined without conventional lacing.

For OEM / ODM development, brands can customize mesh density, reinforcement materials, strap width, fastening layout, toe proportions, internal lift geometry, heel structure, lining, cushioning, outsole compound, tread pattern, colors, branding, packaging, and size ranges. The design can retain its vintage athletic character or move toward a cleaner contemporary silhouette.

Asahihara Co., Ltd. supports last development, upper pattern engineering, concealed-lift construction, material sourcing, sample manufacturing, fitting evaluation, production management, quality control, and bulk production follow-up. Particular attention is given to the relationship between internal elevation, heel retention, and the external proportions of the shoe.

During sampling, the actual 6cm lift, internal foot angle, strap security, heel stability, forefoot pressure, sole flexibility, and size grading should be carefully evaluated. Walking tests are especially important because a concealed lift of this height can significantly affect foot positioning and balance.
