What is a size 6 in men shoes converted to women size?

US 6 is a US womens 7, in the UK they are size for size. But remember toe shape ... size is the size of the tooling to produce the shoes, not foot length. Bizarre I know but we are stuck with it! Toe allowancecs vary from manufacturer depending on their fit characteristics. Most men would not tolerate a womans fitting (sorry but fact of life) so you may want to size up a little.
