Men's Cole Haan Gunnison Slip-On Shoes The rugged leather upper features a bit of preppy cording around the foot that ties smartly on the vamp. The sole and heel features rubber treads to keep you sure-footed whether you’re on foot or behind the wheel. Striking and debonair, the Men's Gunnison Driver is a moc full of unique details. The sole features a flexible rubber nubby driving-style sole and heel protector. Slotted eyelet lacing runs around the upper and finish with a neat tie closure, for a slightly nautical nod. The perfect casual style, pair this with jeans or chinos for a relaxed look.
