Choosing a UK 4 shoe
In our chart a UK 4 fits a foot about 23.3 cm (9.2 in) long. To check your own, stand on a sheet of paper against a wall, mark the tip of your longest toe, and measure from the wall to the mark. Do it in the evening, when feet are at their largest, and measure both feet, because many people have one slightly bigger than the other.
Next to it in the chart, UK 3.5 is 4 mm shorter (22.9 cm) and UK 4.5 is 4 mm longer (23.7 cm). Allow roughly 5 to 10 mm between your longest toe and the end of the shoe, so go by the foot length, not just the number on the box.
If you are between sizes, or your feet are wide, take the larger size, and add a thin insole or thicker socks if it is loose. Brands cut differently, so a UK 4 in one make can fit another make a little long or short; the retailer's own chart and returns policy matter more than any converter.
