We suppose we can forgive the sidecut oversight, though it's hard to understand why it took more than a century to figure out that if a little bit of shape is good, then just a touch more might be-ready?-even better. But why it took so long to discover precisely how much fun a slightly wider ski could be is beyond us. Never mind. Midfats are here now, and they've changed the sport of skiing in wonderful ways. The best of them arc it up on groomed terrain more readily than any straight ski ever did. But it's in soft snow conditions that these beauties truly shine. Crud? Bring it on. Corn? Extra helpings, please. And powder? Pure heaven. Go bigger, faster and fatter than you ever have before. And remember: You don't have to admit to anyone but yourself that it's the skis.
