RAMJET airflow redirection technology for improved footwear thermoregulation

Overview

RAMJET technology is a novel footwear design solution that addresses a persistent challenge in athletic performance: keeping feet cool, dry, and comfortable during high-output activities. By integrating an aerodynamic upper and midsole design, RAMJET directs airflow through the shoe to maximize evaporative cooling in regions of the foot that are typically under-ventilated, including the bottom, arch, and sides. The technology is built on the principle that improved heat and vapor dissipation directly enhances perceived comfort and athletic performance, as supported by published research linking foot temperature and humidity to sock comfort during sport activities.

Beyond performance benefits, RAMJET advances broader product goals including enhanced ventilation, sustainability through glueless construction and responsibly sourced fibers, debris protection, and a distinctive product silhouette that differentiates it in the market.

Technical specifications

Key features and design elements:

• Aerodynamic upper design that channels airflow through the shoe to reach under-ventilated areas of the foot
• Glueless midsole and footbed construction eliminating adhesives while maintaining structural integrity
• Strategic material mapping based on aerodynamic and thermodynamic properties to optimize ventilation in targeted zones
• Debris ingress protection maintained despite increased airflow
• Sustainable fiber and material sourcing integrated into the design framework

Validation results:

In controlled testing using a modified UA HOVR Phantom 3 SE, the RAMJET-equipped shoe demonstrated an initial 100% increase in drying speed compared to the unaltered control shoe. As the front regions of both socks dried, evaporative differences tapered off, and the unaltered rear sections of both shoes dried at the same rate, confirming that the technology successfully redirected airflow specifically to the modified regions.

Technology readiness level

RAMJET is currently at an advanced prototype stage. Proof-of-concept validation has been completed, demonstrating measurable improvements in drying speed and airflow redirection. A structured 10-month development plan is underway with three primary objectives: developing a working prototype that significantly increases heat and moisture dissipation, implementing glueless attachment technology, and confirming sustainable fiber sourcing and testing. The project timeline progresses through prototype development, glueless attachment integration, sustainable material sourcing, final product development, finalization, and review and presentation. The team is actively seeking industry partnership to support further testing, access to materials, and laboratory resources needed to advance toward full product implementation.
