Dynafit TLT5 Mountain TF-X Alpine Touring Ski Boots 2012: The Dynafit TLT5 Mountain TF-X Alpine Touring Ski Boots are the ideal choice for skiers who demand the best in boots for long distances and high altitude tours. They are also the best option for tours with difficult climbing both on ice and rock, thanks to the short rockered sole and perfect crampon compatibility. The additional Downhill Booster tongue makes it extremely supportive during even the most technical and steep descents, while the racing-derived Ultra-Lock system allows for incredible cuff rotation and uphill agility with a super fast, single-motion transition from walk to ski mode. Designed for a wider range of users, the Mountain version features a Pebax® cuff for a great combination of lightness and downhill performance.
The Dynafit TF-X Liner is the first liner to combine fully customized thermoform-ability with the durability, comfort, and plastic reinforced tongue of a traditional alpine boot liner. The NEW TF-X liner, specifically developed for freeride-touring boots, is the most supportive, comfortable, and durable thermoformable liner on the market. It’s pre-molded on a very anatomical last and can also be used right out of the box.
Additional Features
New and revolutionary Ultra-Lock System allows simultaneous opening and closing of the cuff buckle while changing between ski and walk mode.
Quick Step-In Inserts provide 70% easier step-in to Dynafit bindings.
Power Strap
Claw Outsole is a mountaineering-focused outsole for better grip and traction on the most difficult terrain. The toe and heel areas are made of a durable and sticky compound for the best climbing performance.
Grilamid® shell is the lightest and stiffest polymer on the market.
Pebax® cuff for a great combination of lightness and downhill performance
Toothed Buckle Catches are designed to match with the Ultra-Lock System. Made of Magnesium, they allow full regulation and adjustability to adapt to different leg sizes.
Flex and Fit
Acti-Flex Zone allows 5mm of flexibility in the toes for maximum agility while climbing and skinning. It’s active adjustment improves power transmission to the skis while skiing and skinning with no negative impact on torsional rigidity or downhill performance.
The TLT5 features the shortest and most compact and rockered lower shell on the market for incredible agility and walk-ability.
Cuff Shape
The innovative Double Tongue System allows incredible agility on the climbing/skinning phase and superior downhill performance once the additional Downhill Booster tongue is added. Inserting or removing the booster tongue is designed for quickness and simplicity.
Driving Spoiler slides inside rear of cuff, allowing the widest and smoothest cuff rotation possible. Once the Ultra-Lock System is closed, it becomes locked with the cuff, building a super-stiff downhill structure.
