Regarding the Sealskin shoes. The width designated is F and that is the widest they were made --it is actually an EE and Dacks always used letters : D = Med. ; E = Wide; F = X- wide. The numbering inside indicates that they were made 1987 in either March or April. The value of such an old pair is exactly as someone has earlier stated, 20. or maybe 30. if the buyer is " really" pumped up about them Daxman ( retired Dack store manger).
