"What Our Gearhead® Experts Are Saying: ""The Monarch BOA is a solid choice if you want style and performance in one package. The dual BOA system dials in a super precise fit, and the Interlock liner system really keeps your heel locked down. It’s lightweight, grippy, and comfortable—perfect for riders who want one boot that handles the whole mountain."" We ride the Nitro Monarch BOA when we want supportive comfort with a stylish edge. Designed with input from team riders like Christy Prior, the Monarch is built to handle everything from stylish park tweaks to deep carves across the mountain. With a medium flex and women’s-specific fit, it’s tuned for versatility—giving us the confidence to explore and the comfort to ride all day. The Dual Zone BOA Fit System delivers a precise, micro-adjustable fit across two zones, while the Interlock liner system ensures our heel stays firmly in place for responsive control. Underfoot, the EVA outsole keeps things light and cushioned, with rubber impact panels adding durability and eco-friendly traction using recycled materials. With its recycled content and plastic-free packaging, the Monarch is as environmentally responsible as it is performance-driven."
