This 3989 Brogue is revamped in after-dark style with panels of Glassine, a leather with a fully reflective finish, complemented by panels finished with a fine geometric emboss. The 3989 Brogue in Ajax/Glassine has the iconic AirWair Bouncing Soles, that are oil-and-fat resistant with good abrasion and slip resistance-and have been since 1960. The shoe is Goodyear welted, meaning the upper and sole are sewn together in a heat-sealed z-welt stitch for enhanced comfort. Material: Leather.
