They are fine for what they are and I would buy them again. They are super tight right now but I expect that will lesson as they are used. At least I hope so!
After trying several brands for comparison sake my firm conclusion is that - These liners are the best ! Pros: Long lasting warmth Thin but sturdy construction that adds no bulk inside boot and holds up to all day wear. Cons: None The fact that they do not have sticky stuff on them is a real plus and makes them very easy to get into a boot. Put a pair in my ski boots today and they worked to keep my feet nice and warm even with the temperatures hovering around 0 degrees F. When we finished skiing close to 6 hours later they were still nice and warm so I took them out of my ski boots and put them into my regular boots - Arrived home an hour later and again, they were still warm so were taken out of my boots and put into my slippers where they have been for the last 2 hours and yes, they are still warm. Amazing. The secret to getting maximum warmth from these liners is allowing them to be exposed to the air for at least 3 minutes BEFORE putting them into winter shoes or boots - If you feel them cooling go indoors and take your boot off for a couple of minutes so the liner can once again be exposed to air.
