Timberland exclusive 6-Inch “Black Zip” Boot is predominantly decked out in a fully black upper with silver hardware. On the upper, a black reflective collar shines brightly as the boot is finished off with black/silver laces and Timberland branding towards the heel. What really sets these boots apart from the rest is the lacing system, which isn’t laces at all but actually a zipper that tightens and loosens the boot from the foot. There's also a pair of black laces if you want to swap out the rope laces. In addition, the 400 grams of Prima Loft insulation will keep your feet warm and dry during those cold winter nights.
