KPnP Scoring Socks Size Calculator

Enter your instep/mid-foot circumference for recommended KPnP E-Socks / PSS size (official worldwide charts – measure around widest part of foot instep, not length)

Note: Official KPnP sizing is based on instep circumference (not foot length). Measure with a soft tape around the widest part of the mid-foot/instep (standing, barefoot). Snug fit preferred for sensor accuracy — size up if between sizes or prefer looser. Toes should be slightly visible per WT rules. Some users size 1–2 smaller than shoe size. Confirm with latest KPnP chart when buying.
