I have order this pair of Birkenstock AZ soft footbed base on price . I never receive the order in the set time , so when I call Amazon customer service , Adam , be very helpful and re-ordered my sandal , ship they overnite . the only issue be that they be a different model and fit differently . I be very happy with the service I receive from Amazon , but next time I should have check to make sure it be the exact model I already have . I do not want the hassle of return they as I order will order the same model as the first time .
