Right in the middle of our final CES podcast, we were mildly interrupted by a man on battery-powered heels. These are Spnkix, a pair of wheel-toting heels that can be lashed to your shoes (Men sizes 6-14, Women sizes 7-15.5). You can expect to push out around 7 miles of coverage on a single charge -- depending on your weight and angle of the surface. Charging takes around 4 to 5 hours, while the battery units are removable if you reckon you'll be making an extended journey. Speeds top out at 10mph, while a wireless controller (that also takes removable batteries) allows you to manipulate the speed, while a stopper on the heel will be familiar to anyone who's roller-skated before. Spnkix Pro, seen here, will set you back $699 and they're available to buy at the source below.
