Returned. too big and insulated. More for cold weather than hot. They are called "desert boots" which is strange because they are insulated and would be very hot in warm weather.
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.
