This is my second pair of Teva Tirra sandals.  They have awesome arch support and are super adjustable.  I have multiple problems with my feet (high arches, high instep, plantar fasciitis and bunions) and these make me forget them.  Comfortable right out of the box. Good for a foot that borderlines on wide.  My only complaint is that the strapping material on this black/white pair is thinner than the solid colors....and therefore the eyelet that the straps feeds through turns sideways as you wear them.  It isn't uncomfortable; it just looks odd.  I sewed some stiff backing onto the strap and it totally fixed it.  So if you don't sew, get a solid color.  You won't find a better sandal.  I live in mine during the warm months.
