Last week was CES, a technology event where businesses introduce us to their vision of the future. Lauren Goode wrote about a pair of high heels:

• Zhor Tech has a pair of heels with adjustable heights. Through a smartphone, the height of the heel can be lowered from about 7.9 centimeters (3.1 inches) to 4.3 centimeters (1.7 inches).
• The soles of the shoe are heated, with temperature controllable via smartphone.
• They also serve as fitness tracking devices, monitoring your activity.
• The footware is advertised as lasting four days on a single charge.
• You can expect to shell out $300 for a pair.
