For hunts and field movement across changing ground, the LaCrosse Women's Alphaburly Aero 15" Dark Shadow 1600G Boots combines waterproof coverage, Solarcore 1600G insulation, moisture-wicking Grid Fleece lining with hand-laid ZXT rubber construction. Solarcore 1600G insulation helps retain warmth for deep-winter and very cold conditions without unnecessary bulk. Underfoot, the Burly Trak outsole helps maintain traction, and the hand-laid ZXT rubber construction construction keeps the boot suited to extended movement in deep-winter and very cold conditions.
