Arch Collapse Video: How Orthotics Work

Sole Supports is an innovative manufacturer of orthotics. Their orthotics are designed to correct foot position, change foot posture and correct foot function during weight bearing activities. The video below demonstrates abnormal foot function and arch collapse, explains the MASS position theory and illustrates some common foot problems which develop as a result of abnormal [...]

Motion Control Shoes May Decrease Fatigue in Runners with Excess Pronation

In a study published this month in the American Journal of Sports Medicine, researchers at the Hong Kong Polytechnic University evaluated motion control shoes in recreational runners with excessive rearfoot pronation. Running patterns of twenty female runners were evaluated over a two day period.

Piriformis Syndrome and Pronation

The piriformis muscle is a small, flat muscle which sits deep in the gluteal region (buttocks). The piriformis muscle originates on the lower aspect of the spine (sacrum) and inserts on the top of the femur (thigh bone). The function of the piriformis muscle is to extend and externally rotate the hip (rotate the hip [...]

Weak Hip Muscles & Overpronation are Risks for Running Injuries

Over half of all runners sustain an overuse injury to their lower extremity every year. Common overuse injuries in runners include runner’s knee, shin splints, Achilles tendonitis, ankle sprains, stress fractures, plantar fasciitis and generalized arch pain. A recent article in Sports Health reviewed the literature from 1980 through July 2008 for common mechanisms related [...]

Calluses in Runners

Common areas for callus development in runners include the area under great toe and at the inside of the heel. Continued rub, friction or irritation can result in blister development underneath the callus, which can be quite painful and limit performance. Aggressively rubbing the callus with a pumice stone, trimming the callus with the razor [...]

Flatfeet In Children: Are Orthotics Necessary?

Many individuals have flatfeet and never have foot problems. In fact, all of us are born with flatfeet and some of the greatest athletes have flatfeet. But, flatfeet are a problem when complete arch collapse is combined with excess inward rotation of the foot and ankle (pronation). This type of flatfoot causes excess stress on [...]

Higher & Tighter Shoe Lacing May Help Runners

To evaluate how different shoelace patterns affect the biomechanics of runners, researchers evaluated 20 experienced runners with six different lacing positions. Foot pronation during contact, tibial (leg) acceleration and plantar pressure distribution were recorded as the runners ran across a force platform.

Flatfeet and Pronation

The characteristic sign of a flatfoot is the low arch. In some cases the arch may touch the floor. In the picture on the left, the heel turns out, the ankle rolls in, the arch collapses and the foot abducts (moves away from the body). Individuals with flatfeet generally have over-pronation. Pronation is the rolling [...]

Trail Running and Your Feet

There are almost 7 million trail runners in the United States and they enjoy fantastic views, clean air and the peace and quiet of the outdoors. Trail running does have it’s own set of risks and injuries. Although many of the same foot and ankle problems a road runner might encounter, a trail runner may [...]

Hiking and Piriformis Syndrome

The piriformis muscle is a small muscle which sits deep in the buttocks over the sciatic nerve. It’s action is to rotate the hip out (external rotation) and extend the thigh back. When the piriformis is tight, is in spasm or on stretch, it irritates the sciatic nerve, which send pain down the back of [...]

Chronic Heel Pain, Obesity and Pronation

Obesity and pronated foot type may increase the risk of chronic plantar heel pain: a matched case-control study. A new study reveals a link between chronic heel pain, pronated feet and obesity. The study included 80 individuals with chronic heel pain and 80 individuals without chronic heel pain. Body Mass Index (BMI), foot posture (foot [...]
