These match my Hoffmann liners exactly. It looks like they are made by the same company.

Ordered as replacements for an old, trusty pair of boots.

I purchased these felt liners knowing full well that I would not be able to return them as it would cost me at least $15+ in shipping fees, about half the purchase price. However, in my defense, I didn't have a choice as I couldn't find any other boot liners, so I took a chance. I did exactly as they directed, measured my foot using paper and pencil, then order from their chart, a size 9; however, this turned out to be slightly small for me. I really need a 10 but given the cost of the return policy I will simply wear them, however, I know they will wear out much faster. So, loss of 1-star has nothing to do with the quality of the product, its prompt arrival or condition. They are excellent! It seems to me that a boot company should understand that if you are going to sell online that you should expect some returns due to sizing issues and to toss the shipping cost upon the consumer which is about 50% the cost of the liner is totally unfair...and certainly no way to obtain customer satisfaction and their return purchases. So, no, even though I now know my correct size I will not be purchasing them again. Please understand what you are purchasing here as the cost to return these comes out of your pocket even if they don't fit.
EDIT: 12/9/2022 These liners are working out so well that I had to change my rating from a 3 star to 4 stars. They are as warm as the original Kamik liners yet much more durable. They still lose a star due to cost to shipping cost ($15) if I had to return but thankfully, they are working out very well.

The liner is pretty much exactly the same as the original liner of my 50 year old Sorel snow boots. I've had a couple other liners but this one seems the best as it has a leather reinforced heal which is where all others have worn out first.
I'm not sure what size the boot was since the info had worn away but think it was 9.5 USA as that's what I wear now. I ordered a size 9 liner and it seemed to fit well in the boot and was comfy and roomy enough for winter socks.
I was really impressed with the service from the Felt Store also. I live in the Pacific time zone and the order had been processed and shipped back east by the next morning after ordering. I received the liners almost a full week sooner than originally promised when ordered with standard shipping. Big thumbs up there!

The liner is wider than the original liner. I can live with it. The original liners are shot after 45+ years. My boots do have vibram soles. That may be a contributing factor.
