Men's Rocky Blizzard Stalker Insulated Boots The Rocky® Blizzard Stalker Waterproof Insulated Boot keeps your feet warm, dry and on solid footing. This boot is made with the Rocky Waterproof system. The system allows air to circulate in, but it keeps water out. It's hard to beat the warmth provided with the Blizzard Stalker. You'll be prepared for any trek through the snow and subzero temperatures because your feet will be wrapped in 1200g of Thinsulate™ Ultra insulation. This boot has great traction and helps you grip the terrain with a multi-directional Blizzard outsole. The Blizzard Stalker also is one tough boot. The split suede with 900 denier high-abrasion textile waterproof upper resists tears that the environment might try to throw at you and provides additional waterproofing.
