Anatomy of a Shoe: Revel IV Polar Boot

It’s time for Anatomy of a Shoe! Get to know this KEEN shoe and what it can do. This time we’re sharing the story of KEEN’s most adventurous winter boot: the Revel IV. It’s equal parts cozy warmth, rugged adventure, and nimble hiker.

Born out of the need for an agile winter hiker, the Revel IV Polar Boot adds insulation, waterproofing, and proven cold-weather traction to become your go-to winter adventure boots. You get the agility of a light hiker with the warmth of a puffy coat. It’s equally comfortable going for a snowy hike, lacing up to shovel the driveway, or breaking trail in snowshoes. The Revel IV is available in several styles: an all-purpose mid-height lace-up, an extra-tall lace-up with double the insulation for the adventurous, or a more casual pull-on Chelsea style boot (men’s sizing only). And they’re all made with one goal in mind: to keep your feet warm, dry, and comfy through chilly winter days.

Why we made it: So you can keep the adventures going when the weather turns cold and snowy.

If you agree that winter is best experienced up close and personal, it’s time to lace up the Revel IV and seize the day. It’s our warmest, driest, and grippiest boot ever. Load your backpack, grab your snowshoes, and head for the hills. The thing about the Revel IV is that it keeps feet warm and dry while you experience winter the way you like best — active and exploring. Here’s how:

A. THE PART: Rubber sole with KEEN.POLAR TRACTION

THE POINT: Snowy trail or icy parking lot? No problem. The lugged and grippy outsole lets you walk through winter with confidence. WinterLab-tested for traction on icy surfaces, KEEN.POLAR TRACTION grips where other shoes slip thanks to microscopic shards in the rubber that dig into cold, icy ground.

B. THE PART: 200 - 400g of KEEN.WARM Recycled P.E.T. insulation

THE POINT: Using recycled plastic fibers keeps millions of P.E.T. bottles out of landfills and the ocean. The same recycled fibers also create warm, low-profile insulation that seals in heat around your feet. The Revel IV packs in 200 grams of insulation in the mid-height boots and 400 grams in the tall models. Plus, the Revel includes a Thermal Heat Shield insole to capture warmth and three layers of heat-trapping materials to insulate feet from the frozen ground. It’s warmth that you can really feel and that you can feel good about thanks to recycled materials.

C. THE PART: KEEN.DRY waterproof protection

THE POINT: Winter may be cold and wet, but your feet will be warm and dry thanks to waterproof leather, PFAS-free water repellency, and KEEN.DRY, a waterproof, breathable membrane that lets moisture vapor escape without letting water in. Go ahead, make fresh tracks, your feet won’t regret it.

-

D. THE PART: Agile, low-bulk design

THE POINT: Hiking through winter has never been easier thanks to the agile, low-bulk design. Just lace ‘em up like your summer hikers and step into winter. They have the same lightweight, go-anywhere feel you expect from KEEN hiking boots.

-

E. THE PART: Comfy midsole cushioning

THE POINT: Want to take advantage of the day and explore a little further, go a little higher? Go for it. The compression-molded foam midsole means these boots are made for walking, all day long.

-

F. THE PART: Famous comfort fit

THE POINT: A little wiggle room for your toes to move means good circulation for your feet. And good circulation equals warmer, comfier feet. The original KEEN fit fans love includes generous space across the forefoot, so feet stay warmer.

-

G. THE PART: Eco anti-odor

THE POINT: That’s right, feet sweat in the winter, too. Our pesticide-free odor control helps keep feet smelling fresh thanks to probiotics, not nasty chemicals.
