Picking the right size ski boots and bindings isn't as straightforward as we'd all like it to be. Water ski manufacturers like to convert foot sizes into "Small," "Medium," "Large", and "Extra Large" boot sizes.
But these size conversions aren't standardized. A pair of "small" boots and bindings from one ski maker might qualify as a "medium" pair from another maker.
