I bought these sneakers because I am on my feet 8 hours a day every day.  They are very lightweight and comfortable. I am trying them for another few weeks before I get another pair because I have flat feet and I want to make sure the shoe has the support and durability to last for a reasonable time...I've had them for two weeks and my feet haven't hurt yet. And I love the black and purple. It fits definately true to size as I am size 11 and they don't go any bigger and they fit.  I am very pleased with this purchase.  Ryka is the best for me anyhow. Great product!
