Parisian Block Heel Sandal in Genuine Leather with Asymmetric Closure
Parisian Block Heel Sandal in Genuine Leather with Asymmetric Closure
A Railway Operator approached us to develop a parisian block heel sandal around a single idea: asymmetric closure, executed in genuine leather. The capsule was destined for Switzerland and needed parisian finishing that reads designer on the rail while staying repeatable in bulk. This case study records the brief, the specification and the delivery.
The challenge
- The previous factory could not hold consistency across sizes
- Fabric hand feel changed between production runs
- Delivery missed the collection launch window

How it was built
- Reference garments and moodboards were translated into a measurement spec, not just photos.
- Genuine Leather was confirmed with lab dips and a hand-feel approval before grading.
- The block heel sandal was prototyped on the fit model, then revised twice before pre-production.
- Asymmetric Closure was applied in a controlled process to keep every piece consistent.
- Bulk ran with in-line inspection; a photo report was shared before shipment.

Result
- 2,400 pieces delivered inside the 10-week window.
- Unit cost held within 3.0% of the approved quotation.
- The a Railway Operator launched on schedule and reordered the same specification next season.
What we would repeat
Lock the colour standard before grading; every downstream approval depends on it.
