Hermes and Devani boots

Best in Show
The suede knee-high with a stacked heel (left) is the Birkin bag of boots: object of desire, trend-defying classic, future icon (Hermès, $2,250). Think ten, 20, even 30 years ahead, and the initial outlay may not seem so outrageous. Coat, Sportmax.

The Height of Fashion: Over-the-knee boots (right) are leading the pack this season (Devani, $165). They camouflage all manner of leg issues (knobby knees, bigger thighs), can be worn full-length or folded down, and look fantastic over leggings or under skirts. Both pairs shown here are in the latest go-with-everything neutrals—beigy grays that you might call (with apologies to the bearded collies) Weimaraner colors. Jacket, 'S by Max Mara. Leggings, Tse.

Michael Kors boots

Stepping Out
The updated scrunch boot (Michael Kors, $895), equipped with an elasticized ruffled top, flatters calves. Crush it down over leggings (Riller & Fount), as shown, or wear pulled up under a knee-length dress. And if you do orange only with black or brown, you're barking up the wrong tree; it's chicer now to juxtapose bold colors—here, a scarlet coat (Moschino Cheap and Chic) and maroon bag (Botkier).
Chloe boots

Old Dogs, New Tricks
The desert boot, a comfort staple since the 1950s, is reinvented as a lace-up heel in its signature sand color (Chloé, $695). The freshest way to wear it is with straight-leg pants (Sportmax) tucked in—the better to see the sharply pointed leather cuff. Wrap, Ralph Lauren Blue Label. Croc tote, Krocoa. On Keazy: Parka, Fab Dog Inc.

Chanel boots

Time for a Walk
A classic square-toe gets an update in fuzzy tweed, and mixed-browns have maximum wardrobe mixability. Keep things playful with patterned tights and a splash of color up top. Coat, Tommy Hilfiger, $380; Macys.com. Tights, Hue, $13, Macy's; 800-622-9748; Hue.com. Boots, Chanel; 800-550-0005 for stores.
Chloe boots

Twinkle Toes
Faux-steel toe-caps and heels with a spray-painted look—graffiti art meets heavy metal—are a witty touch for classic suede knee-highs (Marc Jacobs, $1,000). Pinning on vintage-inspired brooches (R.J. Graziano; House of Lavande) is a brilliant way to punch them up (also a great upgrade for old black boots). Dress, Peter Som. Clutch, VBH. Fishnets, Hue.
Casadei boots - Christian Louboutin booties

A Trend with Teeth
Exposed zippers are everywhere—sometimes functional, sometimes decorative. On this midcalf boot, above left (Casadei, $990), they're both, enabling you to wear the pair half-fastened (the flare makes calves look slimmer) or at their full height. Dress, Michael Kors. Coat, J.Crew. Ring, Mawi.

Beastie Boy: The shoe-bootie with an animal-print cuff, right (Christian Louboutin, $975), is like a perfect pump that grew up and went to Hollywood. Skirt, Erin Fetherston. Rings, Mawi

Give black boots some pop with brightly colored bags (fuchsia clutch, Krocoa; blue purse, Chanel) or mood-changing patterned tights (pinstripes, Hue; lace, Falke).
Coach boots

Asphalt Jungle
Gray is fall's preeminent shade—an excellent base for stronger colors. Snap on your best friend's leash and head for the street in a double-strapped, stacked-heel boot (Coach, $528). Good news for muscular calves: Your legs needn't be pipestems to fit into this roomy, gaiter-inspired style. Coat, DKNY. Skirt, Diane von Furstenberg. Tights, Fogal.

Christian Louboutin boots

Wuthering Heights
Aggressive over-the-knee platforms get toned down with a thigh-length swingy skirt and a medium-sized bag. The loose, slouchy style leaves room to be cre-ative—scrunch them down, fold them over or wear as is; the classic round-toe and heel means they'll be -doing duty as a wardrobe staple long after 2009.
