I'm a great fan of Hi-Tec as they both use a last that fits my feet and are reasonably priced (generally) but these are just silly. I quote from the start of the product details:
The Hi-Tec Navigator i Waterproof is an innovative walking shoe with built in Bluetooth® technology to guide you to your destination. [These] revolutionary guidance shoes feature a haptic technology navigation pod in each of the insoles. These will vibrate accordingly to tell you which direction to walk in.
As a friend of mine remarked "Wonder how long before mountain rescue has a call from someone who forgot to recharge their shoes?"
