I purchased a pair of these while on vacation.  I am out of shape and having foot problems.  I am a teacher and on my feet all day, everyday.  It did take a couple of days for me to adjust to the shoe, but it was not a problem.  I just visited with my podiatrist and he told me these would help provide more support to the area I am having problems with.  I love how the bottoms of my feet feel, like walking on a cloud or on marshmallows. I plan on purchasing at least two more pair in the near future.  These were well worth the price.
