I have many foot problems...flat feet, plantar fasciitis, bunions,corns,and toes that were crushed in an accident. After trying on many different shoes without regard to brand or price, I put on a pair of Sketchers Optimize in the sand nubuck.  Initially, the rocking bottoms made me skeptical, but after wearing them around the store for 10 minutes I was convinced that these are worth the high price.  I have now put almost 100 miles on them (mall walking and gentle grade outdoor walking) and love them because I can now exercise without pain in my feet.  They are truly like walking on clouds and as an added bonus I have noticed that my posture has improved.  I have not experienced any knee pain since I started wearing them and my low back pain is gone.

The shoes are very well made...I have not experienced any of the construction problems some reviewers have mentioned... and the nubuck version breathes well.  They are very true to width. I purchased the same size that I usually buy in athletic shoes (I normally wear a half size larger in athletic shoes than dress shoes).

A big bonus is that they came with an extra pair of shoelaces (why doesn't every manufacturer do this?)  The shoes also come with a DVD about the shoes and how to walk in them.

These shoes are probably not for the elderly or people who have balance problems but for me they are an answer to multiple foot problems.  I'm going to purchase a couple more pairs from Amazon.
