Description of Dynafit Zzero 4 U-TF Ski Boots - Women's '09 This is the women’s version of our best selling model, the ZZero 4U. This is the most striking and most downhill-oriented women’s specific boot in the collection thanks to the PU reactivity (the fact that the shell becomes stiffer when cold ). With it’s women’s-specific liner and new cuff spoiler (lower and wider, to better fit the lower women’s calf muscles) the ZZero4U Women is simply a well-designed, women’s fitting, big mountain performance, A.T. ski boot. It is supplied with a Multiform liner, the lightest and most durable traditional liner on the market and with our super-lightweight and warm TF-Thermoformable liner.
