The future of our health could lie in what we wear on our feet. Google has announced that they are working on a new smart shoe that will help us live healthier. Google is said to be designing footwear embedded with sensors that can tell how much the user weighs and monitor their activity. The shoes can also be programmed to detect falls, meaning they could appeal to older customers as they could send alerts to families or caregivers. Despite all the positives in helping us live healthier lives, some people fear that insurance companies may use this information to determine how much their customers should be charged for coverage given their exercise rates.
