Bought these because I stand  for 10 hours a day at my job.  I also do an incredible amount of walking.  I did a lot of research and finally called the company for suggestions.  I thought sure the springs in the front and back would give me a little energy when I walked.  I've had shoes that actually magnified your energy and propelled your step a bit.  I was disappointed that they did not do that.  I was also disappointed that you couldn't feel a  little give or bounce when you stood still and flexed up and down.  Again,  I have had shoes that you could feel them giving and taking on the shock of your step.  Still I gave them a try.  My feet did hurt but not as much as some other shoes so I tried to wear them.  After two weeks I developed a terrible pressure in the ball of my right foot like the springs were coming through the inside of the shoe.  When I finally took the shoes off the ball of my foot was actually swollen and sensitive.  When I called the company the woman that had been so helpful and assuring this was a  great shoe if you needed to relieve pressure on the balls of your feet now says,  this shoe is only to absorb shock not to relieve pressure....I'm sorry isn't relieving pressure on our joints and feet the reason we buy a shock absorbing shoe?  Of course now I'm the fool that expects miracles from her shoes but at the time I was making the purchase I had come to the right place. I'm still not convinced that the shoe isn't just falling apart after two weeks.  She never offered to let me try a more padded version and now says I may not be able to return them because I have been wearing them for two weeks and I wore them outside.  What a waste,  even on sale they were pricey especially for two weeks of wear.
