Designed to relieve fatigue and heel pain caused by plantar fasciitis, RBX performance orthotic insoles feature a generous gel heel cup that absorbs impact with every step to keep you comfortable and stable all day long. Great for work shoes, casual athletics, hiking, walking, running, and long days of standing, RBX insoles use adaptive memory foam to cushion and contour to the unique shape of your feet. Perfect for low-profile footwear, these 3/4-length insoles feature a flexible cross-vented torsion cage that promotes arch stability, improves balance, and strengthens lateral support. Hydrowick fabric technology helps control moisture to keep your feet cool and dry during exercise and daily activities. The 3/4-length insoles don't require any trimming- just slide them in, and they're ready to go.
