The Tecnica Firebird 110 offers maximum power, support and stability for speed freaks to fly down the mountain. The anatomic fit with asymmetrical toe box and various customisable options makes the Firebird 110 comfortable to wear no matter how long you're out chasing your best time. The Tecnica Custom Adaptive Shape shells and liners have revolutionised the fit and personalisation of ski boots. The C.A.S shell features an anatomical shape to better match the natural shape of the foot for a better out-of-the-box fit. Dimples on the shell offer a lower surface tension and facilitate heating to make customising the shell easier and to retain the new shape more accurately. The dual-density liner is less prone to mis-shaping over time and has been shaped for optimal comfort and heel hold.
