“We are developing a performance-grade daily trainer engineered for long-term joint health and natural foot mechanics. The shoe must preserve structural alignment while maintaining modern comfort.” BİOMECHANİCAL SPECİFİCATİONS: • Drop: 5mm • Stack height: 22mm heel / 17mm forefoot • True anatomical toe box (foot-shaped, not tapered) • Structured heel counter (firm external or internal) • Moderate torsional rigidity (not floppy, not stiff plate) • Forefoot flexibility zone at metatarsal heads • Stable heel base (slightly wider than upper) MİDSOLE MATERİAL DİRECTİONS: • Bio-based EVA blend (minimum 30–50% plant-derived content) • Target density: ~0.20–0.25 g/cm³ • Medium firmness (not max soft) • Compression set under 35% after 24h compression test OUTSOLE: • Natural rubber blend (high abrasion resistance) • Strategic rubber pods in high-wear zones • Not full-coverage heavy slab UPPER: • Recycled engineered knit (polyester-based but recycled) • Or bio-based polyester alternative • Reinforced midfoot wrap • Breathable structure • Minimal overlays SUSTAİNABİLİTY DİRECTİON: • 50–70% bio-based or recycled content target • No toxic solvent-based adhesives (water-based bonding) • Modular outsole if possible • Designed for 800km durability ALL İN ALL: 1. This is a health-focused performance daily trainer. 2. It must look modern and wearable. 3. Biomechanical priorities: • 5mm drop • Anatomical toe box • Structured heel • Stable midsole platform 4. Sustainability target: • Bio-EVA midsole • Natural rubber outsole • Recycled knit upper 5. Design must signal engineered intelligence, not orthopedic. SİDE NOTE: ON CLOUD SHOES ARE A GOOD EXAMPLE AS MODERN BUT WE HAVE TO MAKE OUR OWN UNİQUE DESİGNS
