The Charmoz is a stiff, B2 rated boot, ideally suited towards winter mountaineering, summer alpinism and general mountain terrain. 

Developed by Scarpa for their Rebel range of footwear, the NAG last was designed to provide exceptional comfort for technical use with a strong emphasis on focusing the climbing power over the toe/front of the boot. This creates a more precise, technical mountain fit. 

Sandwiched between the sole and the footbed is Scarpa's ACTIV Impact Technology. This system used for sole construction uses materials with physical and chemical characteristics, meaning it's able to absorb negative impact with the ground, increasing shock absorption and maximising the energy used in the movement. On the front of the Vibram sole is a flatter, thinner region appropriately named "climbing zone". This allows more feel underfoot and increases the practicality while climbing or during approach. 

Scarpa's Autofit Collar massively increases the comfort around the back of the foot by adding padding to specific areas and shaping it in a way that reduces stress that rests on the Achillis and malleous area. Adding further comfort is a memory foam system. The way this works is the natural heat of your foot will warm up the memory foam attached to the heel of the boot, therefore moulding it to your foot and providing a more secure fit as your foot is in contact with the upper of the boot a lot more than without. This technical solution to a better fit is extremely light and breathable and will recover back to it's original shape after every use. 

An issue that arose with many older stiffer boots was that to gain the stiffness, the ankle had to be stiff too, therefore reducing the movement around that area. Scarpa's Flex Point allows the ankle to move with complete freedom, even in the stiffest of boots whist maintaining support and confidence on all terrain. 

To increase the fit even further in the Charmoz is Scarpa's speed lacing system. Integrated within the upper are specifically designed eyelets to allow the laces to pass through freely and without strenuous effort, making it simple and easy to adjust the volume and fit of the boot. This system allows the boot to wrap around the foot in a far more customisable and superior way. 

Designed and constructed to last in mountainous terrain; the Charmoz is wrapped in a full 360 degree rubber rand to offer increased durability, protection and abrasion resistance against rocks and technical paths. 

In the past, Gore-Tex has always been the go-to fabric to provide dependable waterproofing, however a different approach has been looked at recently. A fabric called Outdry have set out to revolutionise the waterproof system we use for footwear by looking at what is currently wrong with membrane fabrics and setting out to fix it. The way this works is that the waterproof, breathable membrane is directly bonded to the external layer of the shoe, perfectly sealing any possible water entry point. Another benefit to this technology is that because the membrane is attached to the inside of the outer fabric, the water is stopped straight away rather than after it has passed through many layers of fabric to the mid of the boot. Outdry technology is not an additional membrane, but a new innovation in waterproof fabrics.

Care & Advice

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.

Excellent customer service. Really detailed easy to understand product descriptions on the Trekitt website, and gear reviews on the Trekitt YouTube channel made it so easy to choose the right backpack for me.

Amazing service! Very helpful in regards sizing and what most matched my needs, despite this being done over the internet. YouTube videos of products being examined are very useful also. Would definitely use again, very fast and efficient delivery. Brilliant! Highly recommended!
