What do you mean about Wesco mistakes on the toe box, do you think it is because they are not made correctly ? I don't know if it is because that's the way they are made ,with lower toe box ( whereas the ones i bought seemed to have a taller toe box than the 7400 ) and they should advise to buy 1/2 size larger than with other boots that have taller toe box , like steel toe ones, or if they have had problems making them. Personaly i don't think the D width on the 1339 last is narrower than other engineer boots like Chippewa or RW in D width but maybe it's because i have thin feet . That said RW ones have a quite tight instep , so i suppose people with large feet have problem with that and Wesco seems to be the opposite with extra wide instep ( Chippewa is in between or at least were as they are discontinued !! Sheeeeiiiiiiit !) Personnaly , Chippewa are my favorite , when they are well made and didn't go through QC with defects ( but RW can have defects as well , i experienced that as well unfirtunately !) ! I am really frustrated as those Wesco were the ones i liked the best for their look as i don't like the flat toe box on most of the Engineer boots without steel toe ( except the Buco repros and Beck but they don't make sizes over 10 unfortunately whereas many guys have bigger foot than that , especialy nowdays !) . I don't really like their boss round toe either compared to Chippewa with steel toe but maybe Wesco Boss with steel toe have the same round toe appearance as the Chippewa , do they ?
