I have a hard time finding a good-fitting shoe of any kind--I have wide, flat feet and a spine that lets me know when things aren't right.

I have been enormously surprised and pleased how well these Teva sandals work for me.  Their arch has more than I do, but it's supportive.  The footbed is forgiving enough that weight is well-distributed.  And I can wear them comfortably all day.  Great traction too.

Amazing.  A sandal worth trying for others who have a hard time finding _any_ well-fitting footwear.
