ZZero 4U-TF Alpine Touring Ski Boots take Dynafit
's best-selling ZZero boots and add extra downhill prowess thanks to a PU shell. If you want Dynafit
's legendary best-of-both-worlds formula, the ZZero 4U-TF boots offer unrestricted, lightweight climbing, and a redesigned shell and liner specially built for female skiers. Polyurethane construction adds strength and durability, making the ZZero 4U-TF Dynafit
's most downhill-oriented boot.
The ZZero boot tongue is designed to anatomically match the shape of the foot. The tongue is high and stiff enough to provide great downhill support, while the bellows make it soft enough to ensure flexibility when walking. A special tongue insert is anatomically positioned to protect the foot from buckle pressure without affecting walking behavior or flexibility.
TF-Thermoflex Liner - Dynafit's super-light thermoformable liner has a new collar shape for increased comfort and is built with more resistant materials both internally and externally for increased durability.
Polyurethane shell and cuff
Dynafit's ski-walk mechanism allows you to lock your ski position at either 15˚ or 21˚.
Dynafit's patented ski/walk mechanism is regarded as the easiest to operate on the market, and when activated allows for exceptional range of movement, both fore and aft, for 30˚ of unrestricted climbing.
4 Magnesium Micro-Adjust Buckles - These lightweight buckles offer complete customization without added weight. Movable catches and floatable touring hooks allow for easy fit-tuning while remaining lightweight and durable.
Dyna Grip Outsole - Designed for maximum grip in all conditions, this lightweight sole will stand up to long days of rock scrambling. The PU wedge running from heel to toe is lighter than rubber and provides supreme protection against the cold.
Patented Quick-Step-In Inserts - Dynafit's patented tech inserts guide the boot into proper alignment with the binding for easier entry.
