ReTiSense, an Indian-based company, has created a smart shoe insert that can map strain put on feet from running and give real-time suggestions to help prevent injuries, like runner’s knee. The insert, called Stridalyzer, uses sensors that are activated with pressure to map the stress you are putting on your feet and knees.
For example, if the inserts sense you are putting too much pressure on the outside of your foot, the accompanying app will tell you in real-time that you are supernating. That way, you are able to correct your running form before an injury happens.
Stridalyzer just completed its Kickstarter campaign and hopes to be ready-for-shipment by running season this Spring. And if you have particularly sweaty feet, not to worry, because Stridalyzer inserts are water resistant.
