4-5-5 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 medium stiffness (4). The Front-to-Back flex rating (5) gives a medium flex when leaning forward or backwards. And the Lateral flex (5) refers to the flex provided towards the sides of the boot, also a medium range of movement is given here.

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.

NEW Tweaker Cuff – This provides a softer medial flex at the ankle that enables freestyle-focused flex, and 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 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 2 Liner – Comfort and fit are meant for each other, and to guarantee their long-lasting relationship, Forum made this beautiful liner so that you can reap the benefit all season long without getting cold feet.

Gold Cuff Links – Quick and easy internal lacing holds your foot deep in the ankle pocket for no lift and all-day comfort.

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

Footpillow – The Footpillow features superior cushioning and dampening for heavy impacts while providing additional arch support, so you can ride hard all day.

NEW Good Vibes Outsole – This enables a more natural flex due to a multi-pod construction, which lets feet feel the subtle sensations underfoot. In addition, this outsole is made entirely from injective EVA, which makes cushioning super consistent. Also, two pockets of encapsulated FGel deaden the bad vibes and ensure that only the Good Vibes get through.

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.
