Sidi Millennium Fit Chart
Millennium Fit is the result of Sidi's relentless pursuit to create the highest performing and best fitting shoes. Compared to previous Sidi shoe fits, the Millennium Fit features a slightly wider shape which will offer enhanced comfort and better adaptability to the foot.
How to Measure for Size:
- Measure length of foot in centimeters from heel to big toe
- If measurement falls between two sizes, Sidi suggests choosing the larger of the two sizes and adjusting fit with insoles
