Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written extensively about the products that make winter that much warmer — like electric blanketsspace heaterstowel warmers, slippers for men and women, and even some great warm and cheap boots — here we’re rounding up the best boot liners and warm insoles on Amazon, for those who’d just rather repurpose some older rain boots for the cold. (Note that reviews have been edited for length and clarity.)

Best sheepskin insoles

4.5 stars, 686 reviews

“Love these. I bought new snow boots a size up for heavy socks. Added these to the boots and they feel wonderful. May not need the heavy socks. They feel wonderful in the boots.”

Best superthick sheepskin insoles

4.4 stars, 598 reviews

“I have custom-made moccasins, like you see at Renaissance fairs, and I lost my inserts when I washed them last. I’m actually happy I did. These are so much nicer and feel amazing!”

Best fleece liners

4.3 stars, 507 reviews

“I bought these in a medium. I’m a size-seven women’s. I wear them in a pair of rain boots that are one size too big while I tend to our chickens. They were exactly what I was looking for!”

Best fleece liner with cable-knit cuff

4.4 stars, 186 reviews

“These are super warm and soft. They looked too short for my tall Hunters at first, but fit perfectly to line the top with the logo still showing. I can wear thinner socks under these; wool is a bit too thick. The boot socks are plenty warm though.”

Just the cuff

4.5 stars, 555 reviews

“Super cute, I’ve gotten lots of compliments. They’re great because you can wear them with any height boots. They’re well-made and great for those who don’t live in a cold enough climate to wear a full heavy sock. Some socks are just too heavy, so your boots don’t fit, this is the perfect solution.”

Just a reversible cuff

4.1 stars, 301 reviews

“These are adorable and perfect! Arrived faster than expected. I can wear them in every boot color and swap either way. Love, love, LOVE these. Many sellers are trying to get $10 to $20 for ones just like these, and they’re not even as cute or able to swap to another color. Silly. Buy these here for only a few dollars!”

Best felt insole

4.5 stars, 121 reviews

“The product came quick. I never write a review, but this product is great. It was three degrees this morning and they worked like a champ.”

Best pressed wool liners

4.1 stars, 67 reviews

“These warm liners made my Ranger boots better than they were before. My old liners were much thinner. Be careful to measure the sole of your old liner and use the Felt Store’s sizing chart so you get the correct fit. My liners have stretched very slightly, so no pinched toes. Used in an outdoor volunteer activity in northwest Wisconsin (warmer this year than others) and kept my feet warm. Very satisfied!”

Best fleece liners for kids

4.5 stars, 48 reviews

“These boot liners are great. I bought them for my 3.5-year-old daughter to wear inside her rain boots when it’s chilly. We don’t get enough really cold weather to justify buying a pair of snow boots for her. These boot liners keep her feet warm, and she loves that they’re pink.”

Best doggy fleece liners for kids

4.2 stars, 45 reviews

“These really work, and how delighted my 4-year-old was when he looked down at his feet and said, ‘Oh, I have little doggies.’ I had not shown him the animal feature at first because I was afraid he might think them silly, but he loves them and has also commented in a recent storm: ‘Look, Mommy, the doggies kept my feet nice and dry!’ You just can’t beat that!”
