Onyx Coiler Performance, Comfort, Fit

This comfortable, forgiving mid-stiff boot is the easy-to-use, single-dial Boa® Coiler sister of the Trinity. The asymmetrical panels and lace-path design offer substantial support and a fabulous fit. The Bronze-Level Heat Moldable liner with cosy fur inside gives added hold around the ankles. The combination of the asymmetrical boot and heel-collar panels, with the reverse-cut cuff of the liner and flex-panel to accommodate different calf-muscle shapes guarantees a perfect ergonomic connection with the foot and lower leg.
