The 509 Raid Double BOA Boots are insulated winter and snow boots built around a dual-zone BOA Fit System. A tongue-mounted H4 Coiler dial takes up lace slack fast, while an M3 side dial tunes the lower zone for a more even, secure fit. Stainless aircraft-grade braided wire and smoother lace guides keep tension consistent. Waterproof, breathable construction with 600 grams of Thinsulate insulation targets cold-weather riding and deep-winter wear.
