3-4-4 Medial/Front-to-Back/Lateral Flex – Woah, fancy words. Medial means the median flex range, so in the middle of the boot you get a softer stiffness (3). The Front-to-Back flex rating (4) gives a medium flex when leaning forward or backwards. And the Lateral flex (4) refers to the flex provided towards the sides of the boot, also a medium range of movement is given here.

Tweaker Cuff – This cuff provides a softer medial flex at the ankle that enables freestyle-focused flex. In addition, it still has all the toe-to-heel and lateral support you need to power through a heavy landing, and hold that edge when charging at massive features.

Tweaker Shell Construction – Working in harmony with the medial flex derived lower in the boot at the ankle, the Tweaker Shell amplifies this flex by allowing the boot to flex higher on the leg as well. This asymmetrical upper cuff has a lowered, softer medial side that frees up the flex, achieving full tweakability throughout the entire boot without losing any toe-to-heel support.

Forever Fit Construction – Built from the inside out, Forever Fit construction ensures that your boot won’t pack out. Starting from scratch, the guys at Forum re-engineered the entire boot to minimize materials and eliminate any potential slop. They took out so much unnecessary material that these boots measure one complete size smaller than years’ past. However, they still retain the perfect fit inside, from day one to day seventy-five.

Tweaker Liner Panel – Located on the medial side at the top of the liner, this flexible mesh panel provides freestyle flex at even the closest connection point with your leg. Directly against your skin, the Tweaker Liner flexes naturally, maximizing the benefits of Tweaker while providing a more comfortable ride with no gaps or pressure points no matter how hard you shred, press, or tweak.

Level 1 Liner – A pack-proof liner with integrated lacing will keep you riding long after your friends hit the lodge. Full of comfort and support, this is the envy of your buds shredding in a borrowed pair of boots.

Speed Zone – With a quick left and right cord pull, your boots will lace up nice and snug.

Level 1 Footbed – These footbeds offer comfort, cushion, and control. The EVA material keeps your foot comfortably in place through a whole day of riding.
