An agile hiking shoe for multi-day, fast-paced hunting in the mountains or plains. The Ducan High GTX incorporates the benefits of cutting-edge design including Flextron technology which integrates a spring-steel sole as a midsole in the shoe. This prevents deflection of the foot while at the same time providing improved vertical support, resulting in more efficient use of energy on hikes and climbs. The specially designed Vibram sole offers outstanding grip on uneven terrain. The Gore-Tex membrane is waterproof and breathable while the synthetic upper is lightweight. The anatomical last, asymmetric lacing, and mono-tongue for one-sided entry, provides a very good fit. Ideally suited for early season scouting, and spot and stalk hunting in all types of terrain where you need a nimble, lightweight, and comfortable boot.

GOHUNT Stiffness Scale Ducan High GTX - Flex 2
Flex 1 Built for light and fast trekking. Think of your favorite trail running shoes, but capable of rocky demanding terrain.
Flex 2 Flexible enough that they offer out of the box comfort but can handle miles of rocky terrain. Perfectly suited for mild to moderate mule deer, elk, and antelope country.
Flex 3 Ideally suited for mountain hunts with moderate to steep technical terrain where more rigidity is required. Some break-in time required but will likely become your favorite do everything hunting boots.
Flex 4 Best suited for hunts at or above timberline where the terrain gets steep. Flexible enough that it can handle miles of comfortable climbing but stiff enough to offer support and rigidity with a heavy pack.
Flex 5 The stiffest boot options, best for alpine hunting and mountaineering. Sheep hunting, mountain goat, and the toughest of elk and deer terrain.


  • Start by collecting a few things from around your house, including a yardstick or ruler, a soft tailor’s tape or paper tape, a piece of cardboard or printer paper, and a pen.

  • Draw a 90° angle on the cardboard or paper using the yardstick or ruler. The lines should be long enough so that your longest toe touches the horizontal line and the widest point of your foot touches the vertical line.

  • Ensure that you’re wearing your hunting socks while taking these measurements. Stand on the paper or cardboard with your feet shoulder-width apart and place your full weight on both feet.

  • Have a second person mark where your heel and the widest part of your foot lands on the cardboard or paper. Ensure that you’re keeping the pen vertical when making your marks. Leaning the pen inward or outward against your foot will skew your measurements.

  • Place the edge of the tailor’s tape on the straight line and measure the widest and longest point of each foot down to 1/10th of a centimeter.

  • Add both length measurements together and divide them by two. This is your length measurement.

  • Add both width measurements together and divide them by two. This is your width measurement.

  • Record your measurements and refer to the GOHUNT Sizing Guide and Staff Reviews to find the right boot size for your foot profile.


  • Measure your feet with the socks you intend to wear in the field.

  • Measure your feet later in the day. Your feet tend to swell slightly as the day progresses.

  • The arch and heel of your foot should feel snug but not tight. Your heel should feel secure in the heel pocket. If your heel lifts up when you step, make sure the lacing is not too loose.

  • Your toes should not touch the front of the boot. You want just enough room to wiggle your toes. When you kick the toe into the floor, you should know where the front of the boot is without your toes hitting.

  • If you're unable to cinch the boot tight enough to prevent heel slip or it allows your toes to touch the end of the boot, you will have a hard time with a heavy pack on steep downhill descents and you’ll want to size up.

GOHUNT Return Policy
If you should need to return a boot, they may be returned within 30 days of purchase for a full refund. Boots should be returned in brand new condition with no wear marks.

You can order another product that best fits your needs or wait until your refund is processed. With all the backcountry hunters we have on staff at GOHUNT, we understand the need and know how hard it is to find a boot that fits your foot.

In the rare case you don't, the GOHUNT staff is on call to make sure you find the right boot for your next hunt.

*We're so confident in our extensive sizing research that if you fully review it, and correctly measure your foot, we know you'll find the boots that fit.


  • Proper boot care can significantly extend the lifespan of your boots. Leather boots, in particular, need to be cared for after heavy use. If your boots are wet and covered in dirt, we recommend cleaning them. If you’re not going to clean your boots, you should still allow your boots to air dry after each use.

  • Remove your insoles and laces after each use. This will open up your boots and allow them to air out. Even if your boots don’t get wet, they will naturally absorb moisture from your feet, especially on multi-day trips. Insoles and laces can be hand-washed in cold water and set out to air dry.

  • Using a boot brush and warm water, remove the dirt from your boots. The warm water will open up the pores of the boot and allow you to thoroughly clean them.

  • For leather boots, you’ll want to recondition the leather after cleaning them with warm water in order for them to remain water-repellant. Applying a waterproofing agent to the damp leather will reclose the pores that were opened up during cleaning. Once you’ve reconditioned your boots, water should bead up when gently poured over the leather.

  • Allow your boots to air dry. Do not use a heat source to dry your boots. The heat could cause the leather to shrink or become brittle, increasing the chances of irreparable rips or creases.

  • Store your boots in a cool and dry place to prevent mildew. We recommend packing a newspaper in the toe box of wet boots to help absorb the moisture and maintain the boots’ shape during the drying process.

  • Take your boots to a knowledgeable cobbler for repairs.


  • For a general-purpose waterproofing product, the GOHUNT staff has found that Granger or Nikwax Waterproofing performs the best.

  • Re-apply this product as necessary or after every use in severe conditions.

  • Please refrain from using beeswax, animal fats, or petroleum-based products on your boots, as these products will void some manufacturer warranties.

  • *Please note that these products may darken the color of any leather.


  • We recommend treating the leather on your Gore-Tex® boots the same as you would on any other leather boot.

  • The Gore-Tex® lining creates a waterproof/breathable membrane on the inside of the boot, but leather uppers still need to be cared for.

  • The durable waterproofness of the Gore-Tex® membrane is not affected by leather conditioners, silicone, oil, or shoe polish.

Solid boot

I've not put as many miles as I'd like on these boots yet, but will still give a review. Initial fit is snug. I almost sent my 12's back for 12.5's, but after roughly 6-8 miles they broke in to fit just right for my foot. So allow for break in unless you're a small 12. As for construction, I don't have a bad thing to say. I really like the single side tongue. Some will probably find it awkward, but coming from running and cycling where its standard you'll have no problems. The hooks for the laces are harder to get into than Salomons, but I've had no problems with them coming out. The strings are absolutely fantastic. My salomon gtx 4d's I had to double knot. These strings have just enough stretch for a solid tie. Less you have to worry about them coming untied in the woods. Nothing like having to stop with a 70lb pack on your back to retie your shoes.

Mammut Ducan high GTX

Great boot - wrong pair shipped and sent back, so no trail time. BUT, they felt really great other than the miniscule toe box. I wish Mammut would make an american version of these with a roomy toe box. Lengthwise, they fit 1/2 size too small IMO.

Johnny Frew
First pair of Mammut

I have been very impressed with the comfort these boots have become. Your hearing this from someone that has had feet problems and a couple surgery’s later I am extremely picky what tires get strapped to my feet. They started off too narrow for me, and they did take time to break in. After a few hikes before the hunt I was convinced these were the ones.

Brandon dungey
Great fit

Got these for California high country hunts, fit true to size and have amazing ankle support. Highly recommend

Johnny Frew
Mammut Ducan High GTX is a very good product

The quality is higher than a 5 star! I did find the boots slightly tight on the width, on the first day, but they have since relaxed a bit and have a great comfort level.
Thanks Mammut; nailed it!
