Product Info

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.

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 BucklesThese lightweight buckles offer complete customization without added weight. Movable catches and floatable touring hooks allow for easy fit-tuning while remaining lightweight and durable.
