Fitting Tips:

If you're between sizes, size up for comfort
Different brands may fit differently - always check specific brand sizing
Leave about 1cm of space between your longest toe and the end of the shoe
Consider the shoe style - boots may require half a size up for thicker socks
Feet can swell during the day, so measure in the evening for the most accurate size
Always measure both feet as they may differ slightly in size
For athletic shoes, you may need a half size larger than dress shoes
Leather shoes may stretch slightly with wear, while synthetic materials typically don't
