first time rainbow user , but long time sandal wearer . I hear for such a long time how these be the best ever . I be not a believer that they be better than the rest , but I think a trial be need to see if they live up to they reputation . this sandal exceed all rumor about the shoe . it be double layered so it will be durable , and now with a half of summer of use it look as if it have just a few day . the break-in process take only a few time of use and my happiness level sky rocket . I think its safe to say that I will only be see wear rainbow for year to come !
