Engineered to be lighter, more comfortable and more protective than ever, the Tech 7 Boots deliver exceptional feel on the bike.The TPU lower shell features an innovative design on the shifter area for reduced front roll and easy shift lever control, with a dedicated design for the left and right foot. This area is further strengthened with a metal shank and is reinforced on the toe zone for impact and abrasion resistance. Equipped with a medial and lateral double pivot system for improved levels of flexibility and precision control. Dedicated design on the medial side wall for improving the feel, support, and grip on the bike, while increasing the protection and durability of the boot. New contoured TPU calf protector plate offers effective impact resistance.The main flexion of the boot is supported around the medial and lateral ankle by a low profile pivot system for superior freedom of movement and rider comfort. The front flexion zone features new innovative shock absorbing inserts in the front bellow zone for progressive support. Shock absorbing padding is also strategically positioned on the ankles and shin plate for increased impact absorption. New strap holder design offers maximum rotation and functionality, while reducing excessive rotation. The sole is made with an innovative wear limit indicator embedded in the foot peg area. This layer displays a red layer alerting the rider when the sole is worn out and needs replacing. The boot structure beneath the wear limit indicator is surrounded by a Kevlar® layer that maintains the structure and integrity of the boot while also protecting the boot.Fit: Similar fit and width as previous Tech 7 boots Footbedis moderately wider than the average MX boot Increased foam padding at the ankle creates anoticeably snug fit, requiring extra break-in if you have thick ankles or wintersocks 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, exoskeletonand 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 againstthe bike Protection: TPU shin, heel counter, toe box, achilles and anklebracing system Bellows at the front and rearFront bellows have 8mm of shock absorbing foam andEVA 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 Updatedfoam at the interior of the ankles Approx. 17 mm of shock absorbing foam Ankle bracing connects toachilles bridge TPU bridge across the achilles to protect from impacts Revised shin guard is both stronger and lower profile, improvingrange 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 ontopegs 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 stiffas the Tech 10but still very stiff) MX / dirt rigid)
