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.

Polar Trex

The Polar Trex have really helped Oli enjoy those winter days. Amazed to see his paws dry after a day in the backcountry. Watching him try them for the first time was worth it alone, now he is comfortable all day in the snow.

Excellent quality; but just didn't work out.

The quality of the shoes were excellent, but the design didn't work for my dog. They always seemed to snag her dew claw/pad, even though I did use the socks. I really wanted to love these! I have multiple ruffwear items though, and I definitely recommend the brand as a whole!

Didn’t work out for us

Overall dealing with Ruffwear was fine. Measured, ordered accordingly. Exchanged one pair for different size. Still didn’t work out for us. The cuff rides right under his dew claw. He is used to boots but these obviously bothered him. After adjusting several times, I returned every but one pair that wasn’t in perfect (resale) condition.

My dog loves them!

They were easy to size properly, easy to put on and stay on well.

Great for Backcountry

My dog runs with me when I'm snowboarding and snowshoeing and I don't have to worry about these boots falling off or her feet getting wet and cold.
