1. Buy 30 half-inch or 38-inch sheet-metal screws at the local hardware store. The screws should be long enough to stay firmly in place but not poke you. (Duh.)
2. Screw 14 into the raised lugs on each boot鈥攈alf on the heel and half near the ball. Finger-tighten, then tension slightly with a socket driver.
3. Logging lots of winter miles? Buy the real thing: A.T. Grip Hobnails ($40; ).
