Eco-Friendly Sporty Shoe Design

“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
