INSULATED WINTER DEFENSE. Features an insulated softshell upper for breathable, weatherproof warmth, actively trapping heat to prevent frostbite and discomfort during prolonged exposure to extreme cold outdoor. SOLD IN PAIRS – NOT A SET OF 4. Dogs often have wider front paws than rear paws. That’s why we sell our dog boots in pairs. So you can mix sizes and get the perfect fit on all four paws. A better fit means fewer slips and more miles together. UNYIELDING ICE TRACTION. Equipped with the Vibram Icetrek non-marking rubber outsole and a winter-specific lug pattern for superb, reliable grip on packed snow, slippery trails, and challenging sheer ice surfaces. ANTI-SNOW GAITER, RELIABLE CLOSURE. The pullover stretch gaiter with a robust zippered closure creates an impenetrable barrier against snow and ice, preventing accumulation, freezing, or jamming, ensuring easy on/off and a secure fit. LONG-LASTING WATERPROOF INTEGRITY. The advanced waterproof, windproof, breathable softshell upper is built to maintain its integrity against snowmelt and slush, providing dependable, long-term dry paw protection season after season. Conquer the coldest landscapes in confidence—Polar Trex Dog Shoes are specifically engineered for uncompromising paw protection in harsh winter environments. The advanced upper is crafted from a polyester blend with a weather-resistant (WR) finish (face: 87% polyester, 13% spandex; backing: 100% polyester), delivering a waterproof, windproof, and breathable softshell barrier against snow, slush, biting winds, and ski edges. Combined with robust insulation, this design efficiently traps warmth while still allowing paws to breathe, so your sidekick stays comfortable on long, frigid expeditions. The serious winter grip advantage comes from the Vibram Icetrek non-marking rubber outsole, paired with a winter-specific lug pattern for reliable traction on ice, packed snow, and frozen trails—reducing slips and keeping your canine companion sure-footed, even in the most treacherous conditions. The pullover stretch gaiter with a durable zippered closure works together with a YKK hydrophobic hook-and-loop fastening system to create an impenetrable, stay-put fit, blocking out snow, ice, and debris for effortless on/off even when conditions are unforgiving. Despite the heavy-duty weatherproofing, Polar Trex Dog Booties feature an ergonomic, flexible construction designed for natural stride and unrestricted winter agility. Sold in pairs, they allow for custom sizing on front and rear paws for a flawless, slip-free fit.
