What India is actually asking for

One shoe size is 8.5 mm

A third of an inch — a barleycorn. Half a size is 4.2 mm. So a measurement that is 'close enough' often isn't, and any tool that won't tell you its error margin is hiding something.

Sizes are a brand's opinion, not a standard

There is no enforced international shoe size. Each brand builds its own last, so the same UK 8 differs between two boxes on the same shelf. This is why we show what real buyers report about a brand's fit rather than trusting its chart.

Foot length in centimetres is the only honest number

UK, EU and US numbers all describe the shoe. The centimetre length describes your foot. Measure that once and every chart becomes readable.

Wide feet are not a size problem

Going up a size to gain width makes a shoe too long, so it slides and blisters. Width grades exist for this — New Balance publishes 2E and 4E, and a handful of others do too.
