If you're the type of skier who is willing to go the extra mile for better lines, and doesn't like to be held back by extra ounces and sub-par range of motion in walk mode, then the Atomic Backland Carbon Alpine Touring Boot is everything you need. It's impressively light, weighing in at just over four pounds per pair, and a generous 74-degree range of motion in walk mode perfectly complements its lightweight design by actually allowing you to take full, efficient strides, whether you're in for a long, flat slog or tackling steep switchbacks.
