The race to make running shoes an integral part of the Internet of Things is starting to seem like more of a sprint than a marathon, and Stridalyzer is the latest entrant in recent months to jump in with both feet.

It’s a pair of Bluetooth-connected insoles that sense pressure points in different areas of the foot. A rechargeable battery provides up to 10 hours of running time, powering piezoelectric sensors under the heel, arch, and ball of each foot.

The data streams to cloud servers for processing, which builds up a model of the user’s stride -- including how the stress on the foot translates into stress on the knee, which is where a large number of running injuries happen. Stridalyzer’s mobile app prompts users to modify their technique so as to reduce the potential for injuries. It also provides real-time stress heatmaps, graphs and charts, and aggregate “scores” representing form quality and overall performance.

The company behind Stridalyzer, ReTiSense, is planning to launch an additional premium service that will let running coaches and trainers analyze users’ data and provide detailed, individualized feedback.

The choice to embed Stridalyzer’s components in custom insoles is questionable, as the sole (both inner and outer) is where any shoe takes the worst beating. The company says the insoles are expected to hold up for about a year, which is a short lifecycle even in the fast-paced, “planned obsolescence” world of technology.

Stridalyzer wrapped up its Kickstarter campaign earlier this month, and should ship in April.
