Waterproof, warm, grippy, and supportive—the 509 Raid Boa® Boot checks every box as the most comfortable snowmobile boot ever developed.
509 developed the 509 Raid Boa® Boot for long days in the coldest conditions. From the grippy outsole to the waterproof and insulated upper, it delivers the optimal balance of flex, support, warmth, and comfort, along with maximum durability where it matters most. 509 riders claim it’s the most comfortable boot yet, and with the dual Boa® system, you can fine-tune the upper and lower zone fit with the simple turn of a dial.
