Flux TB 2026 is the flagship, advanced snowboard boot model from the Japanese brand Flux, designed for versatile riding from Big Mountain to the snowpark. Described by Japanese designers and testers as a boot with a medium-stiff base characteristic with a flex of 7/10. When accelerators are attached, the flex increases to 9/10. TB is characterized by incredible responsiveness, instant energy transfer to the board's edge, and unique customization and auto-fit technologies, making it one of the most desired high-end models

1. Lacing System

• Dual BOA System with BOA H5 and M+2 dials: The latest version of the dual BOA system. The upper and lower areas of the boot are adjusted independently with precise H5 (tongue) and M+2 (side of the shaft) dials. These dials feature micro-adjustments in both directions, allowing the boot to be loosened by turning in the opposite direction without fully unfastening the system.
• Flexible Lace Guide: Specially designed flexible lace guide in the instep area. Evenly presses the foot from toes to ankle, eliminating pressure points, ensuring soft hold, and drastically improving blood circulation. 
• Heel Lift Prevention: Integrated technology preventing heel lift during aggressive riding and dynamic turns. 

2. Shell Construction and Stiffness Customization

• Accelerate Tongue System: A revolutionary technical solution from Flux's Japanese laboratory. The boot's tongue features a special pocket in which you can slide dedicated, interchangeable stiffening inserts. This allows smooth changes in boot flex and perfect customization for hard conditions, park riding, or deep powder.
• Side Wing: Unique construction of the outer side panels of the shaft. These wings perfectly fill the space between the boot and the highback of Flux snowboard bindings, ensuring direct contact, immediate board response, and more precise movements. 

3. Inner Liner with Beads Cushion Technology

• ADPTV FIT and F0 Zero Inner with Beads Cushion Technology: The key innovation in the Japanese Flux collection. This is the world's first inner boot system that automatically adapts to the rider's foot due to the use of a special material with microbeads (Beads Cushion). Under pressure and heat, the microbeads naturally shift and perfectly mimic and fill the unique anatomy of the foot and ankle. 
• L-Shape Beads and Heel Lock Harness: Specially shaped zones with microbeads in the shape of an L surround the ankle, and an integrated inner harness ensures excellent, comfortable, and uncompromising heel lock for every rider. 
• Advanced Thermics and Ventilation: Japanese liner materials effectively absorb and wick moisture to the outside, ensuring optimal temperature and dryness of feet throughout the day on the slopes.

4. Sole and Cushioning

• Low-profile sole with cushioning: Designed to maintain the lowest possible center of gravity and maximum, direct feel of the board underfoot. Special shock-absorbing zones effectively absorb vibrations during fast rides on hard edges and cushion feet during landings
