AKU Pilgrim FG GTX MOD Brown Information

Season : 2021S R

Brand : Aku Tactical

Code : AK560.050

This is the brand new Pilgrim FG GTX MOD model based on the AKU Pilgrim M2 GTX. Trekitt were instrumental in getting this boot on the issue list and we are immensely proud that a boot we originally designed in partnership with AKU is now officially recognised by the MOD.

The Pilgrim FG (FG stands for full grain, as in the leather used on the lace placket) provides a supportive and stable platform for Combat High Liability duties. Breathability and quick drying have been massively improved thanks to the new Gore-Tex Performance Lining System that’s made up of a perforated EVA interliner and lighter weight low absorption lining material. In tests, the Pilgrim FG GTX absorbed 50% less water than conventionally constructed Gore-Tex lined boots.

This new FG version features a Vibram Black Nitrile sole unit that makes it more resistant to fuels, chemicals, oil and acids. The Nitrile sole also provides improved resistance to high temperatures whilst still providing grip and stability across a wide variety of terrain.

The key to the comfort and support of the Pilgrim FG GTX is the tried and tested AKU Internal Midsole System which uses an anatomically shaped 3D midsole that mimics the natural foot shape. Normally midsoles are flat and offer no support to the foot, only dictating the stiffness of the boot. With an IMS 3D midsole the foot is cradled in a relaxed position, therefore, reducing fatigue and minimising foot movement. Above the IMS midsole is a layer of high-density EVA, this protects the user from loading forces particularly when carrying heavy packs and provides a layer of protective support for foot rather than it resting on a hard material. Below the IMS midsole is a thicker layer of high-density EVA which absorbs impact forces from the ground.

The original Pilgrim has proved itself on duty and in operation and became the boot of choice for specialist armed forces and emergency services throughout the world. The new Pilgrim FG GTX MOD carries on that legacy and introduces improved breathability and drying times

  • New Gore-Tex Performance Lining System for enhanced breathability and quick drying
  • Gore-Tex performance membrane, 100% waterproof
  • IMS - Internal Midsole System for support and stability
  • Vibram Nitrile sole – resistant to contamination with grip and impact absorption

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:

  1. A piece of A4 paper
  2. A pen or pencil
  3. A floor and a flat wall
  4. A ruler or tape measure

What you need to do:

  1. Put on the socks that you intend to use with the footwear you have selected
  2. Place the paper/cardboard on the floor with one end flush against a wall
  3. 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.
  4. Draw a line just in front of your big toe
  5. Measure the distance from the wall edge of the paper to the line you drew
  6. Repeat the process for the other foot
  7. Finally, check the longer of the two measurements against the table below to find your size
Your measurement (cm) UK Size EU Size
21.7 3 35
22.1 3.5 36
22.5 4 37
22.9 4.5 37.5
23.3 5 38
23.7 5.5 39
24.1 6 39.5
24.5 6.5 40
24.9 7 41
25.4 7.5 41.5
25.8 8 42
26.2 8.5 42.5
26.6 9 43
27 9.5 44
27.4 10 44.5
27.8 10.5 45
28.3 11 46
28.8 11.5 46.5
29.2 12 47
29.6 12.5 47.5
30 13 48
30.4 13.5 49

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

  1. Whip out the removable footbed from the boots.
  2. Put them on the floor about shoulder-width apart.
  3. With your socks on, stand on the footbeds making sure that your heels are right to the back of the heel cup.
  4. 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.

  1. 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.
  2. 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.
  3. 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).
  4. 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.
  5. 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.

  • AKU Pilgrim FG GTX MOD Brown Review by Rob,  On 29/05/2018 09:20:38

    Far improved than the original boot. GTX Extended lining makes the boot noticeably cooler and sucks the sweat out well. Lace lock makes the boot easier to put on. A high leg option would be nice as well as well as an unlined option.
  • AKU Pilgrim FG GTX MOD Brown Review by Steve,  On 28/07/2018 17:12:40

    Great pair of boots. Already have the pilgrim aku desert version so went for the gtx for work. Went for a 10.5 to allow for thick socks. I normally wear 9.5.-10, but have wide feet. The boots are great even with thin socks.. really happy, pricey but you only live once. Trekitt always provide a great service, that’s why I won’t buy anywhere else.
  • AKU Pilgrim FG GTX MOD Brown Review by djmidg,  On 04/10/2018 11:52:20

    Lacing system caters for narrow feet - always a problem with other ops spec boots for me. As commented elsewhere, the lace locking system very useful. Sole isn't as thick as, say, Haix or Lowa, so yet to see what tabbing is like; however, build quality obviously very good. The heel is quite flat compared to other similar boots but looks like it won't crumble after a couple of years like other soles. Looking forward to thoroughly wearing these in. P.S. A higher leg version would be a good idea.
