You will have to hire boots as well. On the plus side (in Austria) Cross Country equipment is much cheaper than downhill kit to hire, the price of boots+skis was only a few euros more than skis only and it should be much easier to get cross country boots that are comfortable.

The only thing I'd to Toby's comments is that the time of the day makes a big difference, especially if it's sunny. Sections that could be intimidating when icy can be quite pleasant when they have softened up and a falling is less painful.
