When a patient tells me their foot pain got worse after trying insoles, my first question is no longer about their diagnosis. It is about where they bought the insoles. In the last eighteen months, the AFA has reviewed a significant and growing volume of counterfeit footwear support products circulating through online retail channels — and what we are finding goes beyond simple ineffectiveness. These products are not merely failing to help. In a measurable number of cases, they appear to be actively disrupting the foot mechanics they claim to support.

The mechanism is straightforward. A properly engineered insole places the arch support at the precise anatomical point where the plantar fascia requires relief. Counterfeit insoles — manufactured to mimic the visual appearance of legitimate products without the underlying engineering — routinely misplace this support point by as much as half an inch. That misplacement does not feel wrong to the wearer. It feels like support. But it is loading the fascia at the wrong angle, creating new stress points while leaving the original problem unaddressed.
