Dynafit ZZero 4U-TF Alpine Touring Ski Boots 2012

The Dynafit ZZero 4U-TF Alpine Touring Ski Boots offer the same bombproof downhill performance and uphill functionality as the rest of Dynafit's acclaimed ZZero line in a PU/Pebax®/Rislan® package that's slightly more durable (and a bit heavier), making the ZZero 4U-TF Dynafit's most downhill-oriented boot. If you're ready to make the switch from your old race boots of yester-year, the ZZero 4U-TF offers the solid power transmission you crave while still providing legendary Dynafit functionality on the skin track.
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.
Shell Materials
Polyurethane shell and cuff
Pebax® tongue
Rislan® powerstringer
Dynafit's ski-walk mechanism allows you to lock your ski position at either 15˚ or 21˚.
Ski/Walk Mode
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.


  • Ability Level: Advanced-Expert
    Whether you charge the steepest lines, carve with race-like precision, hit the biggest jumps or halfpipes; advanced to expert level skis/snowboards are for the more aggressive rider. You will often find the addition of layers of metal, carbon, bamboo, or other stringers in these. These features work to make a stiffer ski/snowboard with more power and rebound.
