Size and fit

This mid-cut backpacking boot from Zamberlan is available for men in a range of whole and half sizes. It’s built on the ZTEC technical last which has less volume in the instep area and more room in the foot flex point. This anatomical design is beneficial for long treks and technical alpine climbs.

The 1000 Baltoro GTX is offered in standard width. Its lace-up closure system permits a secure and customized lockdown to the wearer. Also, the boot fairly runs true to size.


Zamberlan’s 1000 Baltoro GTX is equipped with a Vibram Mulaz EVO outsole. Its surface sports a large contact area filled aggressive lugs for long-wearing grip on virtually all types of surfaces. These self-cleaning lugs also shed mud and debris for slip resistance.

The outsole incorporates a heel brake in its design which aids the user in downhill conditions. The sole’s front section extends upwards to provide extra protection.


This backpacking boot uses a dual-density PU midsole to render optimal cushioning and shock reduction on uneven terrain. It’s paired with a Duraflex footbed to deliver underfoot comfort and arch support to the wearer. A shank is engraved into the midsole for added rigidity. At the heel is a notch for receiving crampons.


The Zamberlan 1000 Baltoro GTX features a fusion of Hydrobloc-treated Perwanger leather and Cordura fabric in the upper. These materials make the boot resistant to abrasions and the elements. A Gore-Tex Performance Comfort membrane lines the upper to provide water protection and breathability.

The boot’s toe box and heel are outfitted with PU-coated rubber rands to enhance durability. Its closure system uses anti-corrosion hardware with an easy-pass design to reduce wear and tear on the laces. The heel’s pull loop allows a gloved finger to permit an easy on and off.
