I had a pair of New Balance 643s and finally wore them completely out after 2  years. They were the most comfortable causal walking shoe I have ever owned.  I went to the local big box sporting goods stores and looked at several walking shoes and ran across these NB 606s which were really nice but none in my size. I found them on Amazon and I'm a happy camper now. I was really amazed at how light the 606s are. Less than a pound per shoe. Very nice gel-padding, low cut heel, and substantial construction. Great price, immediate shipping, no hassles. I will revise my rating from 4 stars to 5 depending on how they hold up. My previous set of New Balance shoes were outstanding and I expect no less from these.
