Superfeet® insoles align and control the motion of your feet, providing balance, support and shock absorption for hiking and other active sports. Features: Orange insoles are made for those who stand for long periods of time or are active and feel any foot soreness after activity or a long day. High-volume insoles take up extra volume in footwear, making them ideal for loose-fitting shoes or narrow feet. Holofiber® topsheets increase oxygenated blood flow thereby improving circulation and muscle energy. Topsheets are treated with Agion to help inhibit odor-causing bacteria. Full-length closed-cell foam provides cushioning, while 3/4-length polypropylene heel caps stabilize feet inside boots. Deep heel pockets, rockered bottoms and strategically placed new forefoot shock pads allow for natural shock absorption. New self-moldable metatarsal domes sit precisely where needed to provide cushion and alleviate pressure. Superfeet recommends this style for use in footwear with removable insoles; also suitable for Gore-Tex® footwear. SUPERFEET SIZING CHART.
