I recently purchased this shoes and have been wearing them ever since.  At first, I had some aches on my calves and abdoment, I guess that was  a good sign.  I am a nurse and at times I have to stand for prolonged periods of time.  This shoes are awesome.  My feet are not hurting like they used to in conventional shoes.  I love this shoes so much that I will purchasing a second pair in the near future.  They are true to their size.
They are roomy enough in the shoe box that my feet are not squeezed like they were in a different pair of so call toning shoes I have.  I wasted $100.
