Alpinestars LE Imperial Tech 7 Boots

The Alpinestars Tech-7 Boots feature an upper constructed from light, innovative microfiber that is flexible and abrasion resistant. Innovative, evolutionary TPU shin-plate construction for greater range of fitment features a reinforced VELCRO® brand closure for comfortable, highly customized closure. The shin zone incorporates a TPU blade system engineered to prevent frontal hyperextension and offer greater flex control. Wide entry aperture for convenience with VELCRO® brand upper closure TPR flap to allow broad ranging calf fit adjustment and support. Medial-facing area is constructed from one-piece TPU panel with honeycomb sculpturing for maximum grip contact with bike and improved heat and abrasion resistance. Top rear flexion of the boot is supported around the calf by an innovative TPU sliding blade system which dissipates the friction.

Fit:

• Similar fit and width as previous Tech 7 boots
• Footbed is moderately wider than the average MX boot
• Increased foam padding at the ankle creates a noticeably snug fit, requiring extra break-in if you have thick ankles or winter socks 

Features:

• Ground-up MX boot redesign, position between Alpinestars Tech 10 and Tech 3 models
• Key updates improve upon the previous Tech 7 while keeping much of the same DNA
• Updated ankle bracing system improves comfort
• Revised achilles bridge

Construction:

• Height: 16.5” 
• Synthetic leather and TPU main construction
• TPU key protection zones, exoskeleton and bracing system
• Synthetic suede at the lower toe box area
• 4 aluminum, low profile buckles (same buckles as Tech 10)
  • Side mounted mid buckles allow better flex
• Gaiter up to just under the top buckle for splash proofing
• Hook and loop upper closure system
• TPR upper grip panel on the medial side for max grip against the bike

Protection: 

• TPU shin, heel counter, toe box, achilles and ankle bracing system
• Bellows at the front and rear
  • Front bellows have 8mm of shock absorbing foam and EVA foam to help absorb impacts
• Extended upper calf area for added coverage
• Re-engineered ankle bracing system
  • Lateral side is now fully encased and more rigid vs the "blade" system from prior generation
  • Updated foam at the interior of the ankles
  • Approx. 17 mm of shock absorbing foam
  • Ankle bracing connects to achilles bridge
• TPU bridge across the achilles to protect from impacts
• Revised shin guard is both stronger and lower profile, improving range of motion
• CE certified to EN 13634:2017

Sole:

• Improved vulcanized rubber sole construction
• Updated the grip pattern
• Grip at the medial side of the sole also creeps up for better grip on the bike
• Wear indicator (shows red rubber) to show when the sole should be replaced
• Fully replaceable, 1 piece sole
• Aramid layer between footbed and red wear layer protects  the foot
• Heel ridge to lock foot onto pegs
• Flatter side too side profile for enhanced stability
• More aggressive “spikes” tread pattern to grab in the mud / dirt conditions
• 8-9 / 10 sole stiffness (not as stiff as the Tech 10 but still very stiff) MX / dirt rigid)
