The F20 Snowboard Boot from Salomon. The new F20 is all about pure, clean, freestyle performance. Its popular, sleek, minimalist design returns this year but with new material upgrades and aesthetic improvements throughout. Featuring a new full synthetic leather upper construction and a new fleece liner material that brings more all-day comfort. When it comes to flex, the progressive freestyle flex of the F20 remains standard and is the reference for how a freestyle boot should feel.
