The Salomon Escape 5 TR is a great cross country ski boot for the newer or less frequent skier to hit the groomed trails in. The Escape 5 is only compatible with an SNS Binding System to give you added control and support as you discover the wintertime. Salomon has used a Sanitized Treatment to prevent odor or bacteria from destroying your boots while you are not wearing them. The wide 105mm last is designed to keep your feet warm and comfortable as you glide down the trail.
