The 509 Raid Double BOA Boots step up with the latest dual-zone BOA lacing system. The new high-capacity H4 reel recoils slack quickly and tightens powerfully to bring newfound fit and response to snowmobile boots. The M3V2 reel on the side adjusts the lower zone for fine-tuned comfort. Stainless, aircraft-grade braided wire and updated smoother sliding lace guides create a more even and secure fit. Waterproof and breathable with 600 grams of Thinsulate insulation to keep you warm and dry.
