(2020·安徽联盟阶段考试)With smart technology increasingly influencing all aspects of our lives, it is only a matter of time before someone invents smart shoes—ones that can be made based on personal needs. Called “ShiftWear”， the sneakers are the brainchild of a team of businessmen, and engineers led by New Yorkbased designer David Coelho.
The adaptable shoes can be customized by using a smart phone app. Shoe owners will have the option of selecting a design from a variety of HD patterns by famous artists or creating one themselves. The company’s founders imagine the marketplace where artists can not only share but also sell their designs to others. Despite being electronic, the designs are clearly visible even in the brightest sunlight. What’s even cooler is that by switching on backlight, users can even show their designs in the dark!
According to Coelho, the sneakers will keep their charge forever if only images are displayed. Though they will need periodic recharging, active users have nothing to worry about. That’s because the shoes are equipped with special WalkNCharge technology that powers the shoes—with every step. Inactive users also have options of charging the sneakers without using wires.
The bottom part of the shoes is covered with Kevlar fibers, a kind of strong material, reducing normal wear and tear. Even better, they are completely waterproof(防水的) and can even be thrown into an ordinary laundry machine for a quick wash! The company predicts that the shoes will range in price from $150 to $1，000 depending on the size of the EPanels where the designs are displayed.
This is not the first time that electronics and shoes have combined. Lithuaniabased iShuh Technologies has come up with a similar concept that connects ereader panels to a smart phone app via the Bluetooth. Whether these smart shoes become as popular as our smart devices remains to be seen, though they surely are attractive.
