Rigid Orthotic Arch Support for StabilityTech Sheet & Size Guide : Here All the features of our Total Support® Original but with a stiffer, more rigid arch support and SpenCore®Forefoot Pad. Perfect for serious athletes needing stiffer, more rigid support. Most rigid replacement insoles offer some motion control and stability but that’s where the similarity ends: Spenco® Total Support® Insoles feature our patented 3-POD® Modulation System: By positioning pods with varying degrees of hardness beneath key areas of the foot, Total Support® Insoles change the ground forces reaching the foot during activity. This tunes the ride for increased performance and superior comfort while helping to reduce over-pronation—a common problem that causes foot, leg and back pain. Spenco® Total Support® Insoles are unconditionally guaranteed for one year. Total Support® Technology aids in the relief of symptoms caused by Plantar Fasciitis.
