In European shoe sizing, an American men's size 10 typically corresponds to a size 43. For women's sizes, an American size 10 usually translates to an EU size 41. However, sizing can vary by brand, so it's always a good idea to check specific size charts when purchasing.

Here's a link to a nice conversion chart. http://www.bata.com/documents/pdf/size_chart_printable.pdf It seems like the EU (French) system is the most foolproof because the sizes go up by 6.6mm each increment. (Other systems seem to be comparatively arbitrary) In other words, look at your children's shoe size on the tongue of the shoe. Hopefully it will have the EU size listed too. Refer to the chart and find your EU size on the "French" scale. From there you should be able to convert your shoe size to anything.
