Lumen was born from all of the stubbed toes rolled ankles & black toenails suffered by the Teva Team over the years. Whether they came during dawn patrol hikes to the surf or late night groover trips around the riverbanks they hurt – a lot. But all of that becomes a distant memory with Lumens Glow From Below. The Lumen was built from the ground up to be the most comfortable flip flop on the market bar none. The topsole features a newly engineered incredibly comfortable foam material & is molded to follow the contour of the foot. Comfort also extends to the strap which is lined with super soft water friendly Trek Dry™ microfiber & backed with a closed cell foam package. At the forefoot Lumen is equipped with the waterproof detachable LED Pedlamp. The Pedlamp is engineered to angle light directly where the wearer is walking fully Illuminating your path. When not in use the Pedlamp can be removed & attached to a keychain (which of course is included) enabling you to keep The Glow From Below™ close at hand – or foot.
