Updates to Zamberlan 996 Vioz GTX

  • A gear designed for both function and style is the Zamberlan 996 Vioz GTX. Its full-grain leather shell provides ample terrain protection, while its Gore-tex lining offers adequate waterproofing.
  • This boot is engineered with the Zamberlan Flex System. It allows wearers to pull off forward flex maneuvers comfortably while getting a steady dose of lateral support.
  • The sole unit features a toe rocker that allows a smooth forward motion. Responsible for delivering traction is the Vibram 3D outsole. Cushioning is brought by a low-density PU wedge midsole.

Size and fit

The Zamberlan 996 Vioz GTX is a mid-cut backpacking boot for both men and women. It has a fairly true-to-size fit. The men’s version is offered in regular and wide widths, while the women’s boot comes only in regular width. Both versions are listed in a number of half and full sizes. The boot is built on the SBPK Performance Fit last which gives the toe box enough wiggle room and the heel zone a nice curve. The wide version comes with the ZWL fit which adds extra space around the forefoot zone. The boot’s lacing system provides a custom lockdown.


Equipped with a Zamberlan-exclusive Vibram 3D outsole, the 996 Vioz GTX grants wearers the ability to gain a secure footing over treacherous terrain and downhill braking. Its heavy-duty lugs are aggressively shaped to give users multi-directional traction. It is resolable which means it can be replaced with a new one when certain preconditions are met. 


Stabilizing the wearer’s footing and providing underfoot comfort at the same time is the 996 Vioz GTX’s low-density polyurethane wedge (moderately raised heel) midsole. It comes with a TPU shank to improve the gear’s overall stability. Additional cushioning is provided by the boot’s 4-mm thick Flex insole. 


The 996 Vioz GTX has a smooth full-grain leather upper treated with Hydrobloc—a Zamberlan cream-based product that enhances the water resistance of leather boots. The main interior of the upper is imbued with Gore-Tex’s Performance Comfort technology, giving the leather boot proper protection from intrusive water. The collar, on the other hand, is crafted with Microtex linings for moisture management around the ankle area. 

Round laces and combination eyelets complete this boot’s svelte upper. The laces are synthetic, while the eyelets are metallic.
