Segmented interior and exterior midsoles resolve stiffness contradictions, enabling independent toe flexion and barefoot-like comfort.
- Footwear Midsole With Articulated Flexion Lines
Varying density polymer foam in the midsole reduces pressure points while maintaining structural stability.
- Articulated Snowboard Boot Shell for Edge Control and Flexibility
Segmented hard-shell cuffs enable lateral flexibility while rigid toe and heel pegs secure the binding for precise edge control.
- Braided Footwear Layer Encasing Midsole
An integrated braided layer system encases midsoles and plates, reducing material waste and production time.
- Interchangeable Footwear Sole Elements with Force Sensors
Segmented support elements secured by elastic bands allow users to customize cushioning based on real-time force data from integrated sensors.
- Orthopedic Slab Deflecting Proximal Phalanx for Foot Stability
A slab under the big toe deflects the proximal phalanx upward to correct abnormal foot alignment and alleviate pain from over-pronation.
- Wearable Insole Force Sensors for Gait Analysis
Piezoresistive sensors embedded in layered insoles measure multi-directional limb forces for real-time pose detection.
- Expandable Thermoplastic Polyurethane Beads for Low-Temperature Foam Processing
Lower hardness expandable TPU beads reduce energy consumption during foam production while maintaining structural stability.
- Dual Impact-Attenuation Footwear Heel for Foot Orientation Control
A dual impact-attenuation system segments the footwear heel into members with distinct force resistance profiles to manage ground reaction forces.
- Footwear Sole Resilient Projections for Impact Absorption
Segmented resilient projections distribute impact forces to resolve the trade-off between cushioning and flexibility in footwear soles.
- Shoe Sockliner with Concave Relaxed Conformation for Wrinkle-Free Fit
A sockliner features a concave relaxed conformation that transitions to a flat in-use shape when compressed inside footwear.
- Curved Treadmill Deck with Detachable Shoe Attachment Resistance
A curved treadmill deck uses detachable shoe attachments to create physical resistance during the foot-lift phase of running.
- Auxetic Footwear Sole with Tensile Strands for Dynamic Fit
Tensile strands secure to the sole periphery limit tension transmission, reducing material complexity and waste while enabling dynamic fit adjustment.
- Footwear Sole Structure with Segmented Haptic Elements
A footwear sole structure integrates haptic elements of varying hardness into a chassis to provide differentiated proprioceptive feedback.
- Footwear Mat-Sock Resilient Mat Adaptation
A footwear system with a soft resilient mat adapts to the foot's shape for barefoot-like comfort.
- Footwear Manufacturing Using Recessed Cushioning for Width Variants
Recessed cushioning members adapt to varying upper widths while securing to a standardized sole assembly, eliminating dedicated tooling costs.
