These GPS tracker shoes from Xiamen Yunduo Network Technology Co. Ltd are designed to help parents locate their children via GPS on their smartphone. The accuracy can reach 5 meters in an open area. Parents can also determine a safe zone for the child. Once the child leaves this zone, the GPS tracker will alert the parents via an app. These GPS tracker shoes can also remember a child's whereabouts. When the child reaches a new place unrecognized by the tracker, it will send an alert at once. Parents can also create a supervisor group and invite other friends or family members to look out for their children together.

Priced at US$48, these shoes are inspired by Marvel and Disney characters, and use a 370mAh polymer battery that can last for 32 hours on one charge. These GPS tracker shoes work with Android 2.3 or above and iOS 6.1 or above. These shoes are water-resistant but are not suitable for washing machine.

Xiamen Yunduo was established in 2013. The company aims to design products that promote a safe environment among children.
