Proscozy, fit solution, versatile, light/warm, durable
These insoles are such a gem - I wear them with various boots (rain boots, winter boots, indoor boots, etc.) to add some warmth and comfort in chilly weather. They work especially well if I need a thicker insole to absorb a small amount of length or width - to ensure best possible fit when wearing socks of various thickness. I wear them so often that I'm about to buy a couple more pairs for fear that they might be sold out. These were such a surprise find (and so inexpensive too!)
I ordered these to go in my leather UGGS to replace the worn out insoles. The only problem with them that I have is that these are so much thicker--it will take awhile for my boots to be comfortable again. Otherwise they are very warm and fit well.
