There's goggles that allow space for wearing glasses underneath. My brother has a Scott brand pair and they look pretty sick. Myself, personally I would hate to wear glasses underneath. It all comes down to price. How much are they? Remember they could break and will you be able to afford to replace them? You could also save up for Lasik next year (I wouldn't do so soon to ski season).
Or you could check out zennioptical.com,

They don't look anything special but are about $75 and will serve the purpose you're after. I used to buy glasses there before I got Lasik and their stuff is good quality and cheap.
