QUEEN: ¾-length insole relieves burning and pain in the forefoot with a built in, T-shaped, metatarsal pad. Burning and pain in the forefoot signals that issues such as splayfoot, metatarsalgia, and nerve damage may be developing or fully present. Queen lifts and keeps the metatarsal bones in the anatomically correct position; this relieves pressure on the entire forefoot. Queen is especially thin and slim: Perfect for even the dressiest high heels, pumps, open toed shoes, and sandals. Made of vegetable tanned leather, hypoallergenic latex, with a self-adhesive backing.
