6 Best Waterproof Pac Boots For Ice Fishing That Handle Extreme Cold
Our guide to the 6 best waterproof pac boots compares insulation, traction, and comfort to keep your feet warm and dry during extreme ice fishing conditions.
The world goes silent when you’re out on the ice. The only sounds are the scrape of your auger, the wind, and the satisfying thump of a fish hitting the deck. But that profound peace can be shattered by one simple thing: the creeping, biting cold that starts in your toes and works its way into your soul. On the ice, your boots aren’t just footwear; they are your primary defense against frostbite and a miserable, cut-short day.

Decoding Insulation and Waterproofing in Pac Boots
Before we talk brands, let’s get our terms straight. A "pac boot" is a specific style of winter footwear, built with a completely waterproof rubber lower "shell" and a more flexible upper made of leather or nylon. The magic, however, is on the inside: a thick, removable liner, usually made of felt or a blend of synthetic materials. This two-part system is brilliant because you can pull the liner out at night to dry by the fire or in your tent—a critical feature for multi-day trips or if you happen to get a boot full of slush.
Insulation in these boots is measured in two ways: by weight (grams of a material like Thinsulate) or by a manufacturer’s temperature rating (e.g., -40°F, -100°F). Take temperature ratings with a huge grain of salt. They are tested in a lab under ideal, active conditions. Your personal circulation, sock choice, and, most importantly, your activity level will determine your real-world comfort. Sitting perfectly still in a camp chair requires far more insulation than actively drilling holes and checking tip-ups.
Waterproofing is non-negotiable. The rubber lower half takes care of standing in slush and water, but don’t forget the upper. Look for water-resistant materials and, critically, a "gusseted" tongue—one that’s connected to the sides of the boot to prevent snow and water from sneaking in through the laces. A wet foot is a cold foot, and on the ice, that’s a safety issue.
Baffin Impact: Unmatched Warmth for Arctic Cold
Stay warm and secure in extreme conditions with Baffin Impact Snow Boots. Featuring a locking snow collar, double buckle fastening, and a multi-layer inner boot system rated to -148 degrees, these boots deliver superior insulation and comfort.
When your biggest concern is simply surviving the cold, you bring out the heavy artillery. The Baffin Impact is that artillery. Designed for expeditions and work in the harshest polar regions, this boot is the pinnacle of stationary warmth. Its claim to fame is a staggering temperature rating, often down to -148°F (-100°C), achieved through a complex, multi-layer inner boot system that wicks moisture and traps an incredible amount of air.
The tradeoff for this furnace-like warmth is bulk. These are big, slightly clumsy boots that feel more like moonwalkers than hiking shoes. You won’t want to walk miles in them. But for long days sitting in a shanty or on a bucket in the bitter, sub-zero winds of the northern plains or Canada, their performance is legendary. Think of the Impact as a piece of survival equipment you wear on your feet.
Sorel Glacier XT: A Classic Design for Deep Snow
If you picture a classic winter pac boot, you’re probably picturing something that looks a lot like the Sorel Glacier XT. It’s a proven workhorse, built for plowing through deep snow and handling seriously cold temperatures. The design is straightforward and effective: a handcrafted, vulcanized rubber shell is mated to a durable, water- and wind-resistant synthetic upper with a prominent drawstring closure to seal out drifts.
Inside, a thick, removable felt liner with Sorel’s Omni-Heat reflective lining does the heavy lifting for insulation. This boot is heavy, and it’s not the most nimble option, but it is incredibly durable and provides excellent protection when you’re trudging through knee-deep powder to get to your spot. It’s a fantastic choice for active ice fishing in regions with heavy snowfall where both warmth and snow-proofing are top priorities.
Muck Boot Arctic Pro: Ultimate Waterproof Comfort
Sometimes the biggest challenge isn’t just cold, but wet. When you’re dealing with deep slush, overflow, or drilling holes that send water gushing onto the ice, the Muck Boot Arctic Pro shines. This isn’t a traditional pac boot; it’s a tall, insulated rubber and neoprene boot. Its key advantage is its absolutely seamless waterproof construction from toe to cuff. There are no seams or materials to fail.
The neoprene upper provides surprising comfort and flexibility compared to a rigid pac boot, making it much easier to walk in. The fleece lining and thick foam underfoot provide excellent insulation, making it a favorite for anglers who are on their feet and moving around. The primary tradeoff is that the liner is not removable, so drying them out after a long day takes more time. But for single-day trips in sloppy, wet conditions, their convenience and comfort are hard to beat.
Kamik Greenbay 4: A Reliable and Affordable Pick
You don’t always need a -100°F rated boot to have a good day on the ice. For the vast majority of ice fishing conditions in the lower 48, the Kamik Greenbay 4 is more than enough boot at a fraction of the price of the top-tier models. It follows the classic pac boot formula: a waterproof rubber shell, a tall 600-denier nylon upper, and a removable 8mm felt liner.
This is the quintessential "get ‘er done" boot. It’s lightweight, simple, and effective. It may not have the bells and whistles or the extreme insulation of its pricier cousins, but it will keep your feet warm and dry for a full day of fishing in typical winter weather. For the weekend angler or someone just getting into the sport, the value proposition of the Greenbay 4 is outstanding.
LaCrosse Ice King: Heavy-Duty and Built to Last
If you measure the value of your gear in decades, not seasons, the LaCrosse Ice King is your boot. These are built like tanks. The construction prioritizes durability above all else, with extra-thick, ozone-resistant rubber and often a heavy-duty leather upper that can withstand years of abuse. They are heavy, and they make no apologies for it.
The warmth comes from a double-insulation system: a removable felt liner is paired with foam insulation built into the boot itself, creating a formidable barrier against the cold. The outsole is typically a rugged, self-cleaning design that provides excellent traction on slick surfaces. This is the boot for the ice fishing guide or the hardcore angler who is out every weekend, all winter long, and needs gear that simply will not fail.
Cabela’s Predator Extreme: Top-Tier Performance
For the angler who wants modern materials and a more athletic fit, the Cabela’s Predator Extreme is a serious contender. This boot blends the pac boot concept with technologies from the mountaineering world. It typically features a very high level of Thinsulate Ultra insulation—often 1,200 grams—which provides incredible warmth without the bulk of a felt liner.
Furthermore, the upper often incorporates a waterproof, breathable membrane like Gore-Tex, offering a higher level of protection for the entire foot. The result is a boot that is exceptionally warm and waterproof but feels less cumbersome and more "walkable" than traditional pacs. It’s a top-tier choice for the mobile ice angler who covers a lot of ground drilling and checking holes and wants maximum performance from their footwear.
Matching Your Boot to Your Ice Fishing Conditions
The "best" boot doesn’t exist. The right boot is the one that matches your body, your budget, and the reality of where and how you fish. Don’t overbuy for conditions you’ll never see, and don’t skimp on warmth if you’re sitting still in the far north.
Think about your personal ice fishing system:
- For the Stationary Shanty Angler: You’re sitting still for hours. Maximum insulation is your priority. Bulk and weight don’t matter. Consider: Baffin Impact.
- For the Active Hole-Hopper: You’re constantly moving, generating body heat. A less bulky, more comfortable walking boot is key. Consider: Muck Boot Arctic Pro, Cabela’s Predator Extreme.
- For Deep Snow and Drifts: A tall boot with a gaiter collar is essential to keep snow out. Consider: Sorel Glacier XT.
- For the Budget-Conscious Weekend Angler: You need reliable warmth for single-day trips without breaking the bank. Consider: Kamik Greenbay 4.
- For the Hard-Use Pro: You need something that will last for years of punishment and abuse. Consider: LaCrosse Ice King.
Remember to size up. You need room for a thick wool or synthetic sock and, more importantly, for a layer of air. Your toes should not be crammed against the end of the boot. That air space is a crucial part of your insulation system.
Ultimately, the goal is to forget you’re even wearing boots. The right pair becomes an invisible tool that lets you focus on the experience—the crisp air, the camaraderie, and the thrill of seeing a flag pop up against a white landscape. So choose wisely, stay warm, and get out on the ice.
