I purchased this shoe because it is almost impossible to find Zig's under 100 bucks, I could not pass up this deal.  I am a runner, and run about 7 miles a day.  I currently run in the Pulse II, and it is a great shoe, no break in time and great support.  This shoe shown here is the Pulse I, it is okay, but made of a different material (not as comfortable as the Pulse II) and it does not feel like it has as much cushion as the Pulse II.  If you are a runner, my advice would be to spend a couple of extra bucks and purchase the Pulse II.
