There are no barnyards in this city.

Which makes you wonder why so many traipse around here in wellies, the staple of farmers, firefighters, and fishermen alike.

Sure, the rubber boots protect feet from dirty curbside puddles. But they’re not exactly warm enough for the chill of winter. (Just wait for the weekend forecast.)

So leave it to Hunter, maker of the original Wellington boots, to rectify the problem with a new line of fleece boot liners. Shaped like a Christmas stocking, the cozy, knee-length essentials are made specifically for your wellies and work like instant thermal warmers.

Available in pretty colors like navy and aubergine, the liners can be turned over the top of the boot to keep them in place and add a stylish touch (in a peeping sock sort of way).

Something you can be sure looks the urban part, whether you wear them in the city.

Or in a barnyard.

Available at Wink, 188 Columbus Avenue, between 68th and 69th Streets (212-877-7727).
