The Issanto sizing system is based on our shoemaking expertise. Each style is engineered for unrivaled comfort based on its unique design. Sizing rules differ around the world, so we offer a comparison sizing chart.

Issanto offers a variety of widths, “B = Standard”, and “W = Wide”, worldwide. Note that the US Standard width is not equivalent to an EU Standard width. Both, US and EU sizes increase within different mathematical parameters, so we’ve created a sizing chart with the most accurate sizing equivalences.

Issanto works with real widths, so the difference in fitting between a B width and a W width is exactly one size in ball girth within the same length.

A standard‑graded shoe is standard in foot bed, ball girth and boot‑shaft. A wide‑graded shoe is fuller in all those areas.
