I got these for my wife.  She like Tevas and likes the Olowahu style the best.  Her heel doesn't slide to the left or right.  They also have a bit of an arch.  The only thing, they're made of a cushy material that eventually loses support.  Not a complain, just the way they are.  Course, they are sandals and usually cost less than $20 a pair.  Also, The Olowahu comes in lots of colors.  So, you can buy many pair. :-)
