I am on my feet at least five or six hours a day.  The sole of this sandal is very supportive and I can see myself being able to wear these all day without discomfort...EXCEPT...the upper part of the sample has no &#34;give&#34; and quickly begins to cause pressure across the top of the foot that becomes quite painful.  Gonna wear these around the house a bit longer as a test drive...they may have to go back.  Will update.
