The K2 Haven BOA women's snowboard boots are a softer-flexing, all-mountain favorite designed for comfort, progression, and all-day performance. Built with an H4 Coiler BOA® Fit System using TX3 laces for a precise and durable closure, they feature a Fast-In liner lacing system and heat-moldable Intuition® Comfort Foam 3D liner that delivers a personalized fit right out of the box. Internal and external J-Bars lock in heel hold, while a 3-point harness enhances ankle support and stability. Underfoot, an EVA footbed and Harshmellow™ cushioning absorb impacts and dampen vibrations, paired with a lightweight rubber RollSole™ outsole for grip, mobility, and natural flex. Lightweight, warm, and versatile, the Haven is the perfect everyday boot for riders exploring new terrain and building skills with confidence.
