It took some getting used to.  I could only wear for a few minutes each day for about a week to get used to the high arch.  Now, I wear all the time when I am home.  I did get a bit of a rub in the toe  area, so I would suggest "breaking them in" before wearing on long walking jaunts.  I am going to buy another pair.  They are expensive for a flip flop, but feel so good.
