It is bar tacked into place for extra durability. Can be manipulated with mittens. Offset overlapping of the Velcro can accommodate a wide selection of clothing layers. This Cinch-Strap runs between the medial and lateral sides of the heel, right at the ankle, for added control of the gaiter. When the Brooks Ranger Low Overboots are being worn as a mukluk, this strap pulls the foot firmly back into the heel so it fits snugly while walking.
Closure Helps slow the escape of heat from the top.
The Brooks Ranger has proven itself in the harshest conditions imaginable. From the summit of K2 to the Antarctic, it has kept the toes of explorers warm and intact. The Low uses the same foam insulation and is equally effective as an insulator. It is worth noting here that if cold damage occurs inside of either of the Brooks models and a modern expedition quality mountaineering boot, it is due to pilot error, rather than any lack of insulation. The Brooks Ranger and the Brooks Ranger Lows are the warmest overboots on the market and can truly do the job at any cold extreme that a human being can withstand.
