When I was in fifth and sixth grades Reebok pumps were very popular (as were Nike Jordans).  Many years later, Outland Research has recently filed a patent for a high-technology shoe that adjusts its support, depending on the type of activity in which the wearer is engaged.  The soles of the shoes have bladders filled with deformable and electronically activated liquid, which only takes milliseconds to react, so the support of the shoe could be adjusted for hiking or running etc.  To read the patent, click here.
