Plastic boots are sort of a reflexive recommendation for Aconcagua, but not mandatory. That said, I think the Freney Pros ($325) may be a little on the light side, insulation-wise. Better to go with a boot such as the Scarpa Cumbre (US$435, but check www.scarpa.co.uk for Euro rates), which has Primaloft insulation, or the Salomon Pro Thermic ($335; www.salomonsports.com), which has Thinsulate insulation. Both boots offer the comfort of a leather boot, with the warmth of a plastic. And of course they're perfectly fine with crampons. You will, of course, also want to pack some overboots, such as Outdoor Research's X-Gaiters ($106; www.orgear.com).
Have a great climb! That's one very big mountain.
