Convert between US, UK, EU, and Mondopoint (cm) sizing — because a shoe that "runs small" shouldn't mean a blister, a callus, or an ulcer.
Approximate equivalents — brands vary by up to half a size. Mondopoint (foot length in cm) is the most reliable system. When in doubt, measure the foot.
Ill-fitting shoes are one of the most common — and most preventable — causes of foot problems. Friction from a short or narrow shoe creates blisters and calluses; in a diabetic foot with neuropathy, those become ulcers. A surprising share of patients wear the wrong size, usually too small, often because they've "always been a 9."
A US men's 9 is roughly a UK 8 and an EU 42. A US women's 9 is roughly a UK 6.5 and an EU 40.5. Use the converter for exact equivalents.
Mondopoint expresses shoe size as foot length in centimeters (sometimes millimeters). It is the most consistent system across brands because it measures the foot directly.
Poorly fitting shoes are a leading cause of blisters, calluses, and ulcers in diabetic feet. Proper length and width fitting — ideally measured, not guessed — reduces ulcer risk.
You want about a thumb's width (roughly 1–1.5 cm) between your longest toe and the shoe's end, with no pressure on the sides. Feet swell during the day, so shop in the afternoon.
Podo360 helps podiatry clinics document foot exams, track orthotic orders, and keep patients coming back for the care their feet deserve.
