Rise, Reebok Pump 2.0, Rise!

Speaking of wearable tech, Reebok's Pump sneaker is back as the Pump 2.0.  Yes, it still uses an air chamber to mold itself to your foot.  This time around, however, you don't need to use a goofy little pump thing.  Instead, the Pump 2.0 inflates itself automatically after a few steps.  The pump is now located in the heel of the shoe rather than the tongue-placed finger pump.  A valve keeps the pressure from being any more than 5psi, a pressure that the Reebok people say will keep you floating on, well, air.  While the original Pump sold for $195, the new Pump 2.0 goes for just $100.
