The CTBI Hyperpronation Correction System has been developed to address a wide range of needs and individual foot types. Hyperpronation can be a major perpetuating factor for many types of pain, including sciatica, low back pain, hip and gluteal pain, adductor and knee pain, along with many upper body issues. For more background on the role of hyperpronation in sciatic pain, please see Chuck's blog post on this topic.
