Do the anklets realy work letting men know that the wife dates. ? Do the men realy know that’s what it means?

It’s not really that effective since women who aren’t wearing an anklet for that reason may also wear one. The only really effective way is to wear a charm that more clearly indicates her hotwife role. I explain this in more detail in the following post: http://cuckoldmarriage.info/2012/01/hotwife-anklet/
