In 1952, Red Wing Shoe Company introduced Style No. 877 made with "Oro Russet" leather which was tanned using the sap of sequoia bark, yielding a rich color that resembled the coat of an Irish Setter hunting dog - but by the mid-1990's, the now well-known Oro Russet leather had started to appear more reddish from color dye than the original golden brown. This change was not appreciated by customers in in the U.S. - but surprisingly, this redder-hued leather became popular with consumers in Japan, where Red Wing had begun to cement its foothold as one of the most popular shoe brands. So in 1996, the new “Oro Russet Portage” was especially created to appear more reddish brown in order to pay tribute to that special leather - Style No. 8877 is an 8-inch moc-toe that boasts an exclusive Irish Setter printed label, just like they would have in the 90's.
