Good-looking, four-inch heels that actually coddle your feet?Believe it. Cole Haan and Nike have teamed up to design a new line of dress shoes that enlists the sportswear giant’s Air technology for maximum comfort. Zoom Air bags inserted just beneath the lining—identical to the support systems in running shoes—counterbalance the pressure of standing and walking for hours on end, and won’t lose volume over time. Now that’s walking on air.; from $265.
