Patients with certain types of spinal problems benefit from custom made orthotic support (SPS Stabilizers, Shoethotics®, or Sandalthotics®). These devices stabilize the foundation of the pelvis and spine by first addressing structural problems with the feet, thereby reducing abnormal forces and stresses, while enhancing structural and functional relationships.

Understanding Human Biomechanics:
- The joints and muscles of the body function most efficiently when they are in physical balance. Principles of engineering have shown that with any physical entity, whether it is a bridge, a building, or the human body— Structure dictates function.
- The body is a biomechanical kinetic chain where abnormal movements at one line, or joint, can interfere with proper movements at other joints.
- During standing and walking, our bodies are subjected to natural forces and postures that can inflict mechanical stress and strain throughout the interrelated chain of joints and muscles.
- When foot imbalance is present, there is a negative impact on the knees, hips, pelvis, and spine. Some patients must have these abnormal forces reduced before they can achieve improved spinal function.
Understanding Pronation:
- Pronation describes the rotation of a body part downward or inward. It is actually a normal motion that occurs when walking; however, if it happens excessively, pronation can cause global postural problems. The major cause of over-pronation is a decrease in the arch height.
Postural Effects from Imbalances in the Feet:
- A loss of arch height will cause a flattening and rolling in of the foot— this is termed pronation. Because everything is connected, the bones of the leg also inwardly rotate.
- Excessive rotation of the bones of the leg (tibia and femur) will cause unnecessary stresses on the knee as well as twisting of the pelvis and spine. If the pronation is more prevalent on one side, there can be a resultant unleveling of the pelvis and a functional scoliosis.
- Tilting of the pelvis places tension on muscles and connective tissues, which can eventually lead to chronic back problems.
- High levels of heel-strike shock can result from breakdown of the body’s natural “shock absorbers.” The shock wave then transmits up the kinetic chain causing painful symptoms all the way up to the head, slowed recovery of leg and spine injuries, and aggravation of other conditions.
Benefits of Spinal Pelvic Stabilizers:
- Properly fitted Spinal Pelvic Stabilizers support the foot to control excessive and unwanted pronation and supination. This helps to reduce unwanted stress on the body.
- Improved shock absorption reduces repetitive stress on joints and muscles, permitting smoother function and decreasing arthritic symptoms.
- Use of Spinal Pelvic Stabilizers represents a long-term, yet cost-effective intervention for many types of functional and structural problems.
How Spinal Pelvic Stabilizers Work:
- Wearing Spinal Pelvic Stabilizers inside your shoes is similar to placing a shim beneath the leg of a wobbly table: it adds support to eliminate unwanted motion in the entire structure.
- The foot is formed of three distinct arches, which create an architectural vault. The result of supporting these three arches is improved stability and postural integrity.
- Flexible Spinal Pelvic Stabilizers encourage optimal muscle and nerve function by guiding the feet through a more normal pattern with each step taken.
About Foot Levelers’ Spinal Pelvic Stabilizer (SPS) Orthotics:
- Foot Levelers, Inc., a leading supplier for 50 years, creates custom-made, flexible Spinal Pelvic Stabilizers to match each patient’s unique needs.
- Using weightbearing impression images of the feet in the position of function (either from a foam casting kit or a digital scanning system), along with instructions from the healthcare professional,
- Skilled laboratory technicians create unique Spinal Pelvic Stabilizers designed to correct and support areas of weakness.
- The combination of flexible, yet supportive and durable construction materials ensure that the stabilizers will both guide the feet when walking and provide support during long periods of standing.
- Unlike other stabilizing technologies, which use rigid materials to force the feet into a theoretical “ideal” position and may result in muscle atrophy and abnormal nerve proprioception, Foot Levelers’ allow controlled, supported movement for the dynamic human body.
