Introducing the lightest and most flexible shoe Cole Haan has ever created Our legacy of craftsmanship and reputation for innovation come together in a striking new brogue that reconsiders mass make and motion Functional brogue detailing decreases weight and provides breathability while grand Os technology in the outsole provides a supremely comfortable fit The ripstop nylon upper pieces of the oxford are bonded to each other using high frequency welding reducing the number of components on the shoe The knit upper of this style tends to have more give than our other styles as a result we suggest ordering a ½ size down from your normal size
