What is the Tengu Lite?
The Tengu Lite is a lighter, more flexible version of the incredibly popular Tengu mountaineering boot. Featuring a more flexible ankle, a Gore-Tex Elastic Sock fit and AKU's Elica stride system, the Tengu's are about as comfortable and supportive as it gets when trekking and mountain walking.
What are they made from?
The upper half of the boot uses an ultra tough, breathable and abrasion-resistant suede leather with an air8000 construction; air8000 increases the breathability rate by 11 times over 24 hours when compared with a conventionally made fabric. A thick rubber rand is then layered over the lower half of the boot to increase durability even further, while reinforced sections of rubber on the heel and toe increase safety. Underneath this, a Gore-Tex membrane provides reliable waterproofing for variable ground conditions. Moving down, a Vibram Curcuma outsole provides grip and security on the sloppiest of mountain trails. The sole (which has been used on the standard Tengu for years now) also features a deep heel to aid grip when descending.
What are the features?
Elica Stride System: AKU's Elica system, in short, provides more support and a more natural stride compared with standard footwear. AKU's Elica natural stride stystem is a construction which builds on an issue with most boots, the footbed. A footbed which is flat won't provide support and will force your foot to constantly have to stabilise itself, meaning you'll feel achy at the end of the walk (sound familiar?). The way the Elica system works is it follows the natural shape of your foot. The anatomy of your forefoot has been replicated onto the footbed, as well as your arch having support to reduce fatigue over long walks. AKU place a harder, supportive fabric in areas of our foot where we put less weight (for example, the outer of your heel), and a softer, more forgiving fabric on the areas which we place the most weight. This offers the optimum level of support and cushioning for complete comfort. As if this wasn't quite enough, the sole unit also features larger, more prominent lugs in areas which hit the ground first. This increases the grip on varied terrain and naturally adds comfort.
Performance fit: AKU's performance fit ensures a slimmer, more secure and more accurate fit for mountain boots and those that will be used for more demanding situations such as trekking and mountaineering.
Exoskeleton: AKU's Exoskeleton technology is invisible, however within the boot it's doing its job! This skeleton is applied to the midsole of the boot and places supportive pieces of polyurethane around the side of your ankles and heel, providing increases stability and support when walking. Despite offering support laterally, it doesn't limit the boot's comfort in other areas.
Gore-Tex: The Tengu features a Gore-Tex membrane to keep your feet dry and protected when trekking through less favourable conditions. This membrane features millions of tiny holes, holes so small that water can't get through, but water vapour (sweat) can escape.
Vibram Sole: Taking care of the underside of the boot is a Vibram sole. This sole features widely spaced lugs to self-clean as you walk, a flat area at the front for increased precision and a deep heel to dig into deep mud and slop, particularly when descending.
Summary
The Tengu is the ideal boot for those trekking and backpacking through uneven, unpredictable terrain. The long list of technologies and experience makes it one of the most comfortable, supportive and just brilliant boots available for the task at hand.

Here at Trekitt we know all too well of the difficulties people face when purchasing footwear online. The hardest part is being confident that you have picked the correct fitting footwear, so that is what we will cover in this blog (or if you prefer you can CLICK HERE to watch our video).
In our Hereford shop we offer a professional boot fitting service where we assess your feet, find a selection of boots that match you foot shape and most importantly we make sure that they are comfortable. This is easy to do in the shop, where we have access to the right tools, the option of letting you try on as many styles as you like and a knowledgeable member of staff that can communicate directly with you regarding your needs.
But let’s not dwell on what you don’t have, instead we shall teach you how to ascertain your size using some common household objects.
What you will need:
-
A piece of A4 paper
-
A pen or pencil
-
A floor and a flat wall
-
A ruler or tape measure
What you need to do:
-
Put on the socks that you intend to use with the footwear you have selected
-
Place the paper/cardboard on the floor with one end flush against a wall
-
Stand on the A4 paper with your heel pressed firmly against the wall and your foot pointed forward with the edge of your big toe aligned with the edge of the paper.
-
Draw a line just in front of your big toe
-
Measure the distance from the wall edge of the paper to the line you drew
-
Repeat the process for the other foot
-
Finally, check the longer of the two measurements against the table below to find your size

NOTE: The above table is only a guide. Manufactures don’t like to make it easy as every single one of them strays from the measurements above.
So, once you have received your chosen footwear please take the time to do these simple tests to check they are actually the right size and that they fit the rest of your foot correctly.
The length test
-
Whip out the removable footbed from the boots.
-
Put them on the floor about shoulder-width apart.
-
With your socks on, stand on the footbeds making sure that your heels are right to the back of the heel cup.
-
You should now be able to see approximately 2 cm (about an index fingers width) of the footbed poking out in front of your toes.
If you can see this amount of space then you are pretty much on the way to making sure that your boots are the correct size. This space between your toes and the end of the footbed ensures that you will not stub your toes on the inside of the boot when you descend. This can be excruciatingly painful. If you can’t see this amount of space then it’s a good bet that the boots will be too small.
The heel lift test
This test will tell you if the shape of the internal heel cup matches your heel to ensure it holds you securely, especially when ascending steep ground. We are trying to eliminate the dreaded heel blister.
Before you commence this test it is imperative that you have laced the boots correctly.
-
Tap your heel so it’s as far back in the boot as possible, being sure to keep your foot at a right angle to your leg at all times during the next few steps.
-
Make sure that the laces have no slack in them across the forefoot by starting at the front of the boot and working the slack backwards and to the top. You should just be able to squeeze the end section of your finger under the laces, not easily, but just about.
-
If you are wearing shoes then ensure the last upper part of the lacing is tight, not cutting off your circulation tight, but certainly comfortably snug as this will hold your heel back in the heel cup and will reduce any excess slipping (If you are wearing boots, this will be the eyelets that sit just below/inline the ankle).
-
Please also make sure when trying out boots that use all the lace hooks, don’t be tempted to leave the top one undone as your foot needs to be held securely right in the back of the boot.
-
Now that your boots are done up properly stand up on your tiptoes and walk on the spot on the balls of your feet as if you are walking up a steep hill. If your heels lift more than approximately 5mm from the footbed you may need to pull the laces tighter, or the boots may just be the wrong shape for you.
The toe wiggle test
This test is designed to check whether you have enough room around your toes. Your toes need to be in a happy place, they need plenty of room to wiggle without being squashed together, or cramped in from above. However they don’t want to be swimming around in acres of space either, this will cause friction blisters and stability problems when traversing hillsides. So, with the boots done up properly, walk around your house and make sure that your toes can wiggle freely.
Home Trial Period
However, even after the most rigorous assessment and testing, there is no better way to be absolutely sure than to have the boots on your feet for an extended period of time. We therefore offer our Home Trial Period which gives you the opportunity to wear the boots around your house to give you an indication of how they feel before you venture outside. We recommend that during the Home Trial Period that you wear the boots for as long as possible and at different times of the day, wear them up and down stairs, when moving around and when resting, you can even sleep in them if you want.
IMPORTANT NOTICE: During the Home Trial Period we insist that the boots are worn indoors only. All footwear must be returned in a new and perfect condition with the original packaging and a proof of purchase. We retain the right to refuse to refund or exchange if footwear shows any sign of being worn outside.
