Which of the following is an indicator that the shoe may have poor fit?

Wrinkles in the arch area of a shoe can indicate a poor fit because they suggest that the shoe is not contoured properly to the shape of the foot. A well-fitting shoe should conform smoothly to the foot's anatomy without excessive gathers or creases, especially in critical areas like the arch—where support is essential. If wrinkles are present, it may mean that there is either too much material or that the shoe is not positioned correctly on the foot. This misalignment can lead to discomfort and inadequate support, which can exacerbate foot conditions or lead to new ones.

While persistent foot pain, over-flexibility, and slippage of the heel also signal issues with shoe fit, the presence of wrinkles specifically highlights the shoe's inability to adequately support the foot's natural structure in the arch area. Recognizing this detail is crucial for fitting shoes that promote overall foot health and comfort.
