Many of the critical comments here seem to focus only on the high price for these devices, but what about the clunkiness factor?

- These "shoes" weigh in at 4.2 lbs each, which IMO makes it prohibitively tedious to deal with. In comparison, a typical cushioned running shoe weighs in at around 11 ounces.

- The extra height off the ground results in a loss of stability and, consequently, a loss in dexterity.

- It seems to function best when moving in a straight line, but impractical otherwise (like turning a corner).

Perhaps there will be improvements to address these issues in later iterations, but if the novelty isn't that big a deal, you may as well just get a pair of rollerskates.

Dunno, people have marched in terrain plenty long in pretty heavy boots and strapped full of equipment. Turns out leg muscles are pretty strong and when you walk on flat surfaces you really don't lift your feet very much.
