PT91 US8D Approximately 26cm RED WING 2218 Logger Boots This model was manufactured before 2000. The inside is relatively clean as insoles were worn. There is scuffing on the heels and scratches on the toes. The dirt on the soles of the shoes has been cleaned as much as possible. Please understand that this is a used item. Regarding the markings "PT91" and "PT99" Symbols such as ANSI, (ANSI) PT83, (ANSI) PT91, (ANSI) PT99, and ASTM indicate that the steel toe (steel toe) of the safety shoes meets certain quality standards. Some Red Wing boots and shoes sold in Japan have steel toes, and these have these quality standard symbols somewhere on the product. These standards were initially set by ANSI (American National Standards Institute), and the standards were updated over time, along with changes in the symbols marked on the shoes. The changes can be roughly explained according to the manufacturing year of the shoes as follows: Red Wing steel-toe shoes manufactured up to around 1982... "ANSI" and symbols are printed somewhere on the product, for example, on the inside of the shaft of engineer boots. From then until around 1990... "ANSI" and "PT83" and other symbols are printed on the inside of the shaft of engineer boots. From then until around 1992... The marking changed from being stamped on the leather of the product to being on a sewn-on tag. The tag has "ANSI" and "PT83" and other symbols printed on it. From then until around 2000... The tag has "ANSI" and "PT91" and other symbols printed on it.
