On our product pages, La Sportiva sizes are shown in US (EU) format: the US size first, with the European size in parentheses. Men's models use the US men's size and women's models use the US women's size.
More sizes means a better fit! La Sportiva shoes are built on European half sizes which are smaller increments than US half sizes. This gives us five extra sizes per size run, which gives you a better fit!
