Vasque Inhaler II GTX Hiking Boots
The Vasque Inhaler II GTX hiking boots deliver waterproof breathability without the weight penalty. We built this boot for hikers who clock serious miles on technical terrain—rockfields, scree slopes, wet forest crossings—and need a boot that moves fast while keeping feet dry. The Gore-Tex membrane seals out water and mud while venting heat, so your feet stay comfortable through four-season use.
Our mid-height cuff provides ankle support on uneven ground without restricting range of motion during scrambles or creek crossings. The dual-density EVA midsole absorbs trail shock mile after mile, while the Vibram Contact Grip outsole holds fast on wet granite and loose dirt. Whether you’re logging long approach hikes or carrying overnight gear, the Inhaler II GTX balances protection, traction, and all-day comfort.
- Gore-Tex waterproof breathable membrane
- 1.8mm suede leather and abrasion-resistant mesh upper
- Dual-density EVA midsole for cushioned stability
- Vibram Contact Grip outsole with 4mm lugs
- Molded TPU heel counter for locked-in fit
Upper construction and breathability
We combined 1.8mm suede leather panels across high-wear zones—toe cap, heel counter, lace eyelets—with breathable nylon mesh at the instep and collar. This hybrid construction sheds weight while maintaining structure where boots take the most abuse. The Gore-Tex lining sits between the outer materials and the internal footbed, forming a continuous waterproof barrier from toe to cuff.
Vents woven into the mesh sections allow hot air to escape during steep climbs, so sweat doesn’t pool inside the boot. The same Gore-Tex membrane technology we use across our waterproof lineup keeps the Inhaler II GTX protective in rain, snow, and stream crossings without turning your boots into sweatboxes on dry summer trails.
Midsole cushioning and trail stability
The dual-density EVA midsole layers a firmer heel wedge under a softer forefoot foam. That combination absorbs impacts when you step down onto rocks while providing enough firmness to prevent ankle roll on off-camber trail sections. We shaped the midsole with a slight rocker profile, promoting a natural heel-to-toe transition that reduces fatigue over long distances.
A molded TPU shank runs through the midfoot, delivering torsional rigidity when you’re edging on narrow trail ledges or balancing across log bridges. The shank stops short of the forefoot, preserving flex for scrambling moves and uneven ground.
Vibram outsole traction
Lug pattern and rubber compound
We spec’d Vibram’s Contact Grip rubber for the Inhaler II GTX outsole—a compound that balances durability with sticky traction on wet surfaces. The 4mm multidirectional lugs bite into soft dirt and trail mud, while wider heel lugs provide braking control on steep descents. Siped edges cut through surface water on granite slabs and wet roots.
The outsole wraps slightly up the toe rand, guarding the leather upper from abrasion and giving you a secure platform for toeholds during scrambles. Vasque designed the lug spacing wide enough to shed mud quickly, so the tread doesn’t clog on mucky spring trails.

Questions about the Inhaler II GTX
Yes, the Inhaler II GTX features a Gore-Tex membrane that provides complete waterproof protection. The membrane is sealed continuously from the toe box through the cuff, blocking water from rain, puddles, and stream crossings while allowing sweat vapor to escape. For best performance, keep the upper materials treated with a water-repellent conditioner and inspect seams periodically for wear.
A men’s size 9 Inhaler II GTX weighs approximately 1 pound 14 ounces per boot, or 3 pounds 12 ounces for the pair. Women’s sizes average slightly lighter due to smaller construction. This weight places the boot in the midweight category—lighter than traditional leather backpacking boots but heavier than ultralight trail runners.
Most hikers report minimal break-in needed for the Inhaler II GTX. The combination of supple suede leather and flexible mesh panels conforms to your foot shape within two to three short day hikes. We recommend wearing the boots around the house with hiking socks for an hour or two before your first trail outing to identify any pressure points and adjust lacing.
We built the Inhaler II GTX for technical day hikes and fast-and-light backpacking on variable terrain. The boots excel on rocky trails, scree slopes, wet forest paths, and moderate scrambles. The mid-height cuff and dual-density midsole provide enough support for overnight packs up to 40 pounds, while the lightweight construction favors hikers who prioritize speed and agility over maximum load-carrying capability.
The Inhaler II GTX uses a cemented outsole attachment rather than a stitched or bolted construction, which makes professional resoling difficult and often not cost-effective. With proper care and rotation, the Vibram Contact Grip outsole typically lasts 500 to 800 trail miles depending on terrain and hiker weight. When the lugs wear to 2mm or less, we recommend replacing the boots to maintain traction and stability.
After each hike, remove the insoles and allow the boots to air-dry fully in a ventilated space away from direct heat. Rinse mud and debris from the exterior with cool water and a soft brush. Every few months, clean the Gore-Tex lining by hand-washing the interior with a mild soap solution, then rinsing thoroughly. Avoid fabric softeners and harsh detergents, which can degrade the membrane’s waterproof properties.
Treat the suede leather panels with a wax-based conditioner every 20 to 30 trail days to maintain water repellency. Before applying conditioner, ensure the boots are clean and dry. Test any new product on a small hidden area first to confirm it does not darken or stain the leather.
Vasque produces the Inhaler II GTX on a medium-volume last for men and a slightly narrower women’s-specific last. We do not currently offer dedicated wide or narrow width options for this model. Hikers with wider feet often find success sizing up a half size and using the speed-hook lacing system to customize forefoot volume. Those with narrow feet may benefit from aftermarket insoles with higher arch support to reduce internal space and prevent heel lift.
