Ensure Your Patients Are Wearing Healthy Summer Footwear

Discover More About Custom Flip-Flops

By: Dr. Mark Charrette

Warm weather has arrived, and more patients and more patients are coming into offices wearing sandals and flip-flops. This time of year presents both a challenge and opportunity for Chiropractors: patients’ shoes can either contribute to their health and whole body wellness, or to greater pain and musculoskeletal imbalance.

Why? With the average American taking 5,117 steps a day, improper footwear can lead to degenerative changes in the muscles, joints and connective tissues in the feet over time. With the body’s foundation compromised, gait, joint movement, circulation and proprioceptive input may suffer as a result. The problem is alarmingly widespread. Seventy-eight percent of American adults over the age of 21 reported in 2012 that they had experienced foot pain or issue.1 Shoes have been implicated as the principal cause of forefoot disorders in women.2

Assess patients’ feet and shoes as part of your normal intake process, and don’t miss the opportunity to talk to them about proper footwear. Ideally, it should provide support, protection and cushioning for the pedal foundation. If a patient’s shoes are poor in one or more of these categories, not only is the spine exposed to abnormal stresses, continued usage could undo your hard work on the adjusting table.

Here’s how to help your patients select healthy, summer footwear.

Look for the Shank

One component of the optimal footwear or sandal is called a shank. A shank is a semi-rigid and semi-flexible material that allows for support and a normal or optimal range of motion when the foot is functional. The typical summer sandal is very thin, not allowing a shank. This will usually result in an unstable pedal foundation.

Insist on 3-Arch Support

Another important component of optimal footwear is the support of the arches—not just the one, but all three: medial, lateral longitudinal arches, and anterior transverse arch. Optimal accuracy can be measured from a weightbearing cast or a functional scan. The height of the arches should be at the relative lowest end of the normal range of motion for that arch. This will allow for normal/optimal motion but block excessive motion, usually pronation.

If the pedal foundation includes a proper shank and all the arches are supported to allow normal motion, it will have a positive effect on the Kinetic Chain and add to the stability of the entire human frame.

Banish Traditional Flip-Flops

Of all the harmful summer footwear out there, traditional flip-flops are perhaps the most damaging. Traditional flip-flops are notoriously flat, offering little support or cushioning to the foot. Not surprisingly, reported rates of heel pain, frequently due to plantar fasciitis, statistically rise in the spring as flip-flop wearers shed their winter footwear in favor of the popular sandal. The problem worsens when the wearer is overweight or sedentary.3

Researchers at Auburn University found that wearing traditional flip-flops can alter gait, “which can result in problems and pain from the foot up into the hips and lower back,” according to biomechanics doctoral student Justin Schroyer, the study’s lead author. “Variations like this at the foot can result in changes up the Kinetic Chain, which in this case can extend upward in the wearer’s body,” Schroyer adds.4

Encourage Healthy Summer Footwear 

Encourage your patients to choose their summer footwear carefully—it’s critical to good health. High-quality, supportive footwear, ideally with support for all 3 of the foot’s arches, gives the body a healthy, solid foundation that is less likely to experience biomechanical problems and is more receptive to Chiropractic care. Wearing custom orthotics in every pair of shoes goes a long way to giving patients the support they need, or consider recommending orthotic footwear and sandals. This helps relieve your patients of the guesswork involved in selecting a healthy shoe, and offers “two-for-one” benefits with built-in custom orthotics. Companies like Foot Levelers offer custom orthotic footwear, including orthotic sandals. Foot Levelers also recently introduced Fiji and Maui waterproof custom orthotic flip-flops, which offer all the fashion and comfort of regular flip-flops but in a healthier model that is perfect for the beach.

Shoes that don’t properly support the feet can significantly interfere with Chiropractic care. Whenever a patient presents with subluxations—especially ones that do not correct rapidly and completely—I strongly recommend an examination of the patient’s feet and usual shoes. Emerging research shows that custom-made orthotics in conjunction with Chiropractic care may be more effective in treating low back pain than Chiropractic care alone.4–6
