How to Measure Your Foot

  • Place your feet flat on a piece of paper and mark your longest toe and the back of your foot. It's best to do this standing and wearing socks
  • Measure the length (cm) straight from your longest toe to the back of your foot using a ruler or measuring tape.
  • Use the chart to find your size.


Men's Caribou 9mm Thermoplus Boot Liner is rated 4.3 out of 5 by 9.
Rated 2 out of 5 by from Caribou 9 mm Thermoplus Innerbo This replacement liner fits very small compared to the original size 9 liner in my older Sorel boots. Very tight fit and a mid weight or heavy weight wool sock will be way to tight. I should have ordered a 10 even though my boots are a size 9. Very disappointed.

Rated 5 out of 5 by from Awesome I have a pair of Sorel Caribou's that I've been using for 10 years now as a snowmobile guide. They get abused at work, from running around in them, gas and oil spilling on them, and all around use. They shells started to crack and I patched them with used bicycle inner tubes and voila, good as new except the liners had fallen apart. I ordered the 9mm replacement liners and it is like the old, abused boots are brand new.

Rated 5 out of 5 by from Sorel's last forever! I am married to the world's best product tester. He is so hard on everything he uses and keeps them forever until they fall apart. I ordered a pair of replacement liners for his Sorel boots that are at least 20 years old. Customer service was EXCELLENT in helping me find the right size. Price was very affordable and delivery was super fast. Sorel is one of the few companies out there that makes products that last forever and provide great service.

Rated 4 out of 5 by from Replacing mens Caribou boot liner The help i needed to replace the liners for the Caribou boots went way beyond what my customer help is like usually from other companies. This women took the time to ask a lot of questions . so she would make the outcome of this conversation a success . My boot had no size markings left anyplace so with patience from her and trials and errors. the sizing was a success . I am wearing them now and very happy . best regards Bill Hines U.S.Army Vietnam Veteran 1969-71

Rated 4 out of 5 by from Sorel Quality While it has not been cold enough yet in Wisconsin to determine if these replacement liners are as warm as the original I am hoping for the best. They do seem a little thinner than the original liner however it seems that the construction (layers) are a bit different. Keeping an open mind and hoping with todays technology less is more.

Rated 5 out of 5 by from Oldies but goodies... I bought my Sorel's 40 years ago in NYC one wintry day. They followed me to Vermont, Idaho, Lake Tahoe and Taos over the years. When I landed in So Calif., they didn't fit the clime but I kept them, even with the linings a little tattered. When I decided I may have need of them again, I went looking to replace those liners and was gobsmacked to find them for sale by Sorel, of all people. Quick phone call got me a friendly gal who was happy to help me figure out all what I owned, even though they were made before she was born. Sizing was an issue - my 1st order was a little large - but swapping them out for a better size was painless. Now they are snug as when new - little mink oil and I'm ready for another 30 years. Thanks!

Rated 4 out of 5 by from Liners that are comfortable I have had my Sorel boots for 34 years, made in Canada. I have replaced the liners many times over the years. Last several have been knock off, not the correct fit, not as warm. Went back to Sorel's liners, will not stray again. I live in an area where we have not had a lot of snow or cold weather for years, this year has been one with lots of cold weather and snow. Great to have my old sorels when I need them, now with new liners.
