Clarks is collaborating with Norton, the British motorcycle firm, on a new collection of biker boots for men for autumn/winter 2014. Key styles in the collection, which is branded Clarks and Norton, are Mellor Top and Norton Zip. Mellor Top features a double stichdown construction, thick hardware and a layered outsole. The Norton Zip style is made using Goodyear Welted construction and comes with reinforced gear change panel, reflective heel tabs, adjustable hardware and constructional screws. Clarks said that for the new collection, its designers were inspired by the new Norton Commando bikes.
