The Nike Air Force 1 07 LX Brown Kelp is one pair in the Toasty pack that gives a heritage favorite a cold-weather reinvention. The upper in quilted textile is made partly from recycled materials that appear via panels in shades of teal, purple, olive-brown and tan. Comfort underfoot is ensured by the rubber cupsole in stark white with a visible Air-sole unit in the heel. The tongue tag displays Nike s pinwheel logo which indicates its commitment to sustainability, while a stitched-on Toasty label adorns the insole in Nike s trademark Volt.
