Haven't had these boots out in F/zero , or lower , but I can tell ya that they keep the feet warm at F/15 . i ordered a half size down as recommended , and the fit is perfect , with a heavy sock . The quality of this boot is way above what I ever expected for the price . I would rate it as High Quality . This is one fine boot !
