Lace-up shoe with detailed stitch work accents a classic. Calf leather upper and lining/rubber sole. Soft flexible sole and removeable XACT construction insole. Using a special antibacterial and anti-fungal formula, these insoles adapt to the foot by allowing individuals to modify the fit of their shoes from day to day. By simply removing the top insole, you can change the width and cushion level. Choose a double level for extra comfort or remove one layer to accommodate for thicker socks or to allow extra room for swollen feet.
