The Teva Women's Lumen sandal was built from the ground up. The topsole features a newly engineered, incredibly comfortable foam material, and 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™ microfibre and backed with a closed cell foam package. At the forefoot, the Teva Lumen sandal 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 and attached to a keychain (included) enabling you to keep The Glow From Below™ close at hand - or foot.
