I've been wearing the men's version of the Minimus shoe for two marathons and training in between. I was delighted to find my size in the women's style (according to the sizes available at the running stores, only women with small feet run in Chicago). They are much more snug on my feet and require thin socks compared to wearing the men's style. I love them and will keep buying them as long as NB makes them! They are way better than the Merrels I bought to replace my first pair of Minimus.
