Snow, so pretty in the air. On the streets, not so much, and our feet bear the brunt. Which brings up the winter-footwear question: In times of ice and slush, shouldn’t function trump form? Luckily, these Marc by Marc Jacobs wellies ($28; 385 Bleecker St., nr. Perry St.; 212-924-6126) address both. They’re waterproof, with adjustable straps to wrap around the baggiest of jeans. The sawtooth soles grip the slippery stuff. The price is great. And they come trimmed in cheery green, yellow, orange, and blue—colors suitable for both sexes.
