WASHINGTON —聽The self-tying shoelaces from 鈥淏ack to the Future鈥� may have seemed like science fiction, but laces developed by German scientists could make the fantasy a reality.
Self-tying shoelaces could be in the near future after engineers from Germany鈥檚 University of Freiburg designed a shoe that can automatically lace up and adjust to cradle your foot, according to .
The shoe, which is in a prototype phase, has a motor with a spring in the shoe鈥檚 tongue that can tighten or loosen the laces.
The smart shoes don鈥檛 even need to be plugged in to work — they run on power generated by the swing of the foot as you walk. The shoes鈥� power can also be topped up by placing them on a wireless charging mat.
Last year, it will introduce its own pair of self-tying 鈥減ower laces,鈥� but they haven鈥檛 hit the market yet.
