These Rossignol BC X6 Cross Country Ski Boots are in excellent condition! These have only been worn twice and are built for backcountry adventures and Nordic fun! These are a men's size 45 EU. For reference, my husband traditionally wears a 10.5 or 11 in US Men's sizes, and has a wider foot. Designed for use on narrow to mid-width (70-90mm) backcountry touring skis and are a blend of lightweight touring performance as well as supportive, downhill performance. These boots are well-insulated and boast a thermo-molded design for extra comfort! These boots have so many great features: - Lining: Polyester Thermo Adjustable Fit THINSULATE - Construction lower: PVC/Cordura - Lacing system: Laces - Lace cover: PVC/Cordura (tall external gaiter that zips over the laces to cover any possible seams and keep out the snow!) - Construction upper cuff: 3D bi-injected, free-hinge cuffs with hook-and-loop powerstraps provide increased stability, power and control - Heel: External 3D plastic reinforcement (super supportive for ankles) - Sole: Nnn BC, nylon shanks in the midsoles provide increased support, stability and durability, and help prevent foot fatigue; dual-density heel counters support and stabilize heels, rugged, nonslip 75mm soles - Closing system: Velcro strap + metallic hook
