The Ruffwear Polar Trex dog boots are designed for warmth, traction, and protection in winter conditions. Insulated upper softshell fabric creates breathable, weatherproof warmth in extreme cold and inclement weather. Ruffwear-designed Vibram® outsole provides optimum traction on frozen surfaces.

Closure system combines hook-and-loop with hardware, cinching around the narrowest part of the dog’s leg to provide a secure fit. Pullover stretch gaiter keeps snow out and improves retention by protecting the hook-and-loop ankle closure from the elements.

Just as you would with your gear, adjust fit and check tension of boots 15 minutes into your activity and throughout the adventure as needed.

Amazing quality

Perfect for my service dog! We live in an area with lots of snow, ice, and salt. These boots are great to protect my pups feet. They are incredible quality and i'm sure they will hold up for years to come. I will deffinetly be buying from ruffwear again and again.

I got these boots for my dogs for the winter for our walks so that he's feet wouldn't get wet/cold nor get the road salt on his feet. These boots are not at all waterproof as they said. His feet got soaked and cold. They where so wet that after I took them off water was dripping out of them. Not worth the money at all!

The features could be better

I expected that they would have more insulation. They are very similar to the regular boot but do have the zip up ankle sock. That feature though, is sewn on top of the part In the shoe that I used to fold over for a more snug fit on my pups feet- leaving them secure but a bit big on top.

I was impressed with the quality, I wished they could have been right for my dog. We humans have different shoes for our feet to feet, these just didn't fit our dog well, he needs something more flexible as he has fleshy pads that spread out when he stands on them and they puff up when not on them. He is a Staffordshire Terrier, I think bulldog types have these type of feet. I will look for shoes more appropriate for him. Maybe Ruffwear will have some.

Polar Trex TM Best winter Boot for dogs!!

Buttons is not your typical Ruffwear customer. He’s a 9-year old Toy Poodle mix who rescued me (he was at the Denver Dumb Friends League) with a host of medical issues, poor eyesight and very sensitive paws. So, even though we are not flying down Colorado Mountain trails every weekend, Buttons does love his walks through Old Town or at the park no matter the weather. Last winter, Buttons walked through a salty slurry of melted snow which I didn’t see in time to pick him up. He let out a painful scream I will never forget; one that made people come out of their houses to see what is wrong with the dog. Since that day, I’ve been on a quest to find the best boot that would protect him and fit him and decided to take a chance on the Polar TrexTM. Quality was never a concern or question as this is my 6th Ruffwear purchase for Buttons (he has the Cloud Chaser, Quinzee, Climate Changer, Front Range Harness and Load-Up Harness) but getting the right fit was given B is so small (he’s a XXS in the Ruffwear apparel). As I suspected, they were a little too big for Buttons but was able to make it work by getting the Bark’n Boot Liners (socks). I got the Polar TrexTM in September which gave me time to figure out how to make the boots work and get B use to them before the snow flies. Today, was the first day of snow in Fort Collins and I’m happy to report the Polar TrexTM are AWESOME!!! Thank you, Ruffwear!
