Although custom foot orthoses (CFOs) are routinely prescribed as a conservative intervention, evidence from large clinical cohorts remains limited. This study aimed to characterise patients with PCFD seeking orthotic care, examine demographic factors associated with pain improvement, evaluate clinical and self\u2010reported outcomes following CFO use, and explore potential interaction effects of CFOs on clinical improvement across sex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective analysis of clinical records between January 1, 2016 and May 31, 2025 extracted 130,365 appointments across 25 Canadian pedorthic clinics, further extrapolated into 669 PCFD encounters and 12,621 asymptomatic controls.

Unilateral PCFD limbs demonstrated significantly higher FPI scores (flatter feet) than contralateral healthy limbs. Both sexes demonstrated significant pain reduction following CFOs use, with females reporting higher pain at baseline and follow\u2010up. Mean pain decreased from 6.52\u00a0\u00b1\u00a02.56 at assessment to 3.69\u00a0\u00b1\u00a02.52 at follow\u2010up (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.0001).
