Two American MBA students are working on the creation of the "Stridekick," a small disposable device that attaches to a shoelace and determines the total amount of miles that have been logged on that particular pair of shoes.
The device also alerts the runner once certain mileage levels are passed, "allowing the individual to make a more informed and healthier decision about replacing the shoes," according to a press release.
Considering both the creators are male, I have a simple suggestion for the grantees: if you're worried if your tennis shoes are too old, ask a girl.
Apparently, podiatrists and running experts agree that running shoes should be replaced every 350-500 miles. This is typically long before external signs of wear are evident to the runner. For more about the StrideKick, just read more
The Stridekick consists of a force sensor, micro controller, and display housed within a small plastic shell. The grant will be used to develop a fully functional prototype, including packaging/logo design. With the Nike + Ipod Sport Kit and now the Stridekick, it seems our sneakers are getting a real makeover.
