Heated insoles are nothing new. Yes, ski trips! Now, a European company called +T wants to bring heated insoles into the future by turning them into an Internet of Things device. The company launched a Kickstarter this past week for its +Winter heated insoles, and unlike similar products, these insoles wirelessly charge, pair with an app over Bluetooth to set a temperature and monitor battery life, and have an accelerometer built-in so they turn on whenever a wearer starts walking.
