The comfort level of these sandals are a 12/10, I could live in them & I owned my current pair for over a year. Recently I went on an island vacation and these were  the only sandals I brought to wear. Salt water and Birkenstocks don't mix, my feet have been stained orange for days now. So if you want your feet to look like you have self tanner on, then go ahead buy these. But if you don't want your feet to look like an umpa lumpa Orange, wear these on dry land only.
