STRIDE is a fully wearable sensor platform that gives runners professional-grade gait insights through their Garmin watch. A custom insole captures foot pressure signatures while an IMU tracks foot path throughout each step, compressing biomechanical data into a 20-byte packet for seamless Bluetooth Low-Energy transmission. The Garmin ConnectIQ app displays live foot-strike heatmaps and post-run stride analytics, enabling runners to improve form, efficiency, and injury prevention. The lightweight clip-on design integrates with standard running shoes, delivering lab-style analytics on any run — no specialized equipment required.
