These inserts are so easy to use and they can be transferred from boot, to shoe, to boot as often as you like. I usually keep them in my winter or rain boots but occasionally I will put them in my fashion boots for work. The cushion really does provide comfort and they work perfectly in any kind of shoe. Save $2 using this link and enjoy dry, warm feet all winter long. And don't forget to join Influenster for your chance to test products for free in exchange for a simple review.
