Debunking the Myths

“Only 1% of the 322 articles reviewed displayed consistent, reputable, and scientific evidence-based information. The authors concluded that the majority of these published articles focused on generating, rather than testing, hypotheses.”

“Cushioning often presents a ‘comfortable’ feeling initially, but it provides a false sense of security by offering benefits that are, for the most part, superficial. Cushioning products mitigate vertical shock by less than 10%, at best.”

“Horizontal forces – rather than vertical forces – contribute most significantly to foot pathologies.”

“The consistent use of the most effective shock absorbing insert (providing medial arch support with heel cupping) did not prevent lower limb pain among healthy soldiers in basic training, and in fact, the insert may have actually caused some injuries - Thirty-eight percent of those issued inserts had lower limb pain problems compared with 29% of those not issued inserts and 38% of those who bought their own.”

“…natural gait is impossible for the shoe-wearing foot …and it is equally impossible for any orthotic to achieve “correct” foot and body balance …no matter how correct and precise the biomechanical design.”

“Repeating quantitative results has proven difficult, with many researchers unable to confirm the quantitative effects of orthotics or find significant variations in effects.”

“We should have a clear body of evidence that orthoses actually work. Unfortunately we don’t.”

“Contrary to claims of correcting biomechanical alignment commonly made by those who support orthotic use, the relative change in structural alignment is minimal.”
