What he reviews
Review means a working technical check before publication: whether the construction described is the one actually used, whether a material claim matches how the material behaves in production, and whether a test is being described the way the standard defines it. Where a figure cannot be supported, it comes out rather than being softened.
- Footwear development — lasts, patterns, sampling, fit and grading
- Outsole and mould development — tooling, materials and trials
- Footwear materials — midsole and outsole trade-offs
- Testing standards — which test maps to which standard
- Quality control and AQL inspection
