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.

Very disappointed

Really difficult to put them on. No waterproof at all. He used it for less than an hour walk and the smeel on those shoes was horrible. Liners, even though I got one of the larger sizes, was really tight on his paws. Overall, not a good product (at least for us). I was so excited when I read all the good qualities on your site that I thought: this is it, finally I'm ordering a really good dog shoes but unfortunately it was not the case


We regret to hear that the Polar Trex did not work out for Hunter. We would be happy to help figure out a solution for you; please reach out to us through our Contact Us form.

Don’t be fooled by the marketing..

These shoes look great. They look comfy and well made. You can almost imagine wearing them yourself. And here-in lies the problem. They are designed with a human in mind rather than a dog. Yes they are designed to fit a dogs paw, but functionally they are pretty poor. Firstly they are difficult to put on and if you want them to stay on you have to tighten the Velcro so tight they cause discomfort. They don’t take in to consideration the position of the dogs dewclaw which gets squashed. We’ve spent ages searching for lost shoes. The fabric top can not withstand the the dogs claws which rip through within a couple of walks. The Vibram sole looks nice but doesn’t give the dog any grip on slippery surfaces. On a wet walk they fill with water rather than being able to drain. In snow the upper sock part traps snow making the dogs paw cold and again causing discomfort. Don’t be fooled by the lovely marketing, these are not a suitable shoe for an active dog. It has been an expensive lesson for us at almost £100 for two pairs.


Thank you for your review. The boots do fit many canines, however it is sometimes the case that the boots do not work for some with regards to where the dew claw is positioned. We have not had reported the issue with the soles not offering grip or the issue with the upper part of the boot collecting snow- I will pass your comments onto Ruffwear US who take customer feedback incredibly seriously. Thank you for taking your time to pass these comments on, we are grateful for all feedback so we can improve the design of our products. I am sorry Ruffwear was not suitable for you on this occasion.

Helps our dog...........

We only use one for the front paw that had to be partially amputated. When she wears it she puts pressure on the paw, but when she doesn't she holds the paw up so we know it works. Thanks to the designers who thought up such a brilliant idea and was able to manufacturer it so a dog would have comfort when out and about.

Mixed Review

We like the soles of the boots and the quality of the material, but the gator isn't effective for keeping snow out. After about 15 minutes of wear, snow chunks form in between the dogs carpus/wrist joint and she refuses to walk (assuming it is quite uncomfortable to have snow/ice chunks in one's shoes). We will try using a co-band to see it that eliminates the problem, but it adds an additional step which isn't ideal.

Amazing boots!

Best boots I’ve ever used for any of our pooches. They are more of a production to get on than some we’ve tried, but after using them more than 10 times in varying depths of snow we still haven’t lost one! They are quite secure and the dog doesn’t lick or bite at them at all when on the walks. They don’t necessarily keep out snow, but the “gators” do seem to add to the security of the fit. Well worth the investment and it is great to be able to order different sizes for front and back feet.
