Smarter strides made possible by Stridalyzer

Knee problems make up a significant percentage of all injuries to runners, hence the common affliction known as runner’s knee. That’s why ReTiSense, the Bangalore, India-based maker of Stridalyzer smart insoles, made the prevention of knee injuries its top priority when developing the product.

Stridalyzer analyzes the user’s stride and gait and can predict if that person is headed for an injury. The insoles have integrated multiple sensors that detect how the user’s foot lands, rolls and pushes off the ground. All the user has to do is put the insoles in their running shoes, turn on the accompanying iOS (and, by the time of launch, Android) app, and start running. Stridalyzer automatically understands the user is moving and will start collecting data about the run from each of the two included insoles. The insoles come with a USB charging cord and each insole battery charges in about 15 minutes.

The insoles are similar in size and use similar materials as the insoles that are used in typical high-end running shoes. The company will design the insoles in just a few common sizes initially, but it will be possible to trim the insoles by one size, using scissors, so they can fit more snugly. The company plans to launch an ExpertConnect premium service to be used with the insoles a few months after the product ships in the spring. The service will enable runners to get more individualized and directed advice from running experts, coaches or trainers. Backers who pledge at least $90 will get the insoles in April or May. ReTiSense is looking to raise $25,000 by Jan. 7.

Certainly the product seems like a steal at the early bird pricing levels, especially when you consider that the similar—but apparently less advanced—UniverSole was priced at $200 a pair. Even at its regular price of $129-$139, many consumers may see Stridalyzer as a good deal.
