What are the Norvan SLs?
The Norvan SL's are quite possibly one of the lightest trail running shoes ever developed - amazingly, this has been done without compromising on any features. Brilliant traction on a wide variety of wet and dry terrain, a tiny pack size and the ability to attach to a climbing harness means the Norvan SLs are truly the pinnacle of fast and light trail footwear.
What are the Norvan SLs made of?
Upper: Arc'teryx are always the kings of detail; after all, their trademark motto is 'obsessive design'. The upper of the Norvan SLs are made using a single layer of TPU mesh with a TPU protective film for added durability and a very high level of breathability when you're out on technical and rugged terrains, whilst keeping the overall weight of the shoe down. The medial heel has a carabiner clip on point making them the ideal partner for multi-pitch climbs. The heel cup is lined with microfibre to ensure a secure no-slip hold around the heel which adds to the stability of the shoe.
Liner: The sockliner is integrated into the shoe - this design ensures the shoe is as comfortable as possible whilst keeping the weight of the shoe to a minimum.
Midsole: The midsole uses a Super Light EVA with an anti-fatigue EVA insert - this helps to protect your joints and muscles and adds to the overall all-day comfort of the shoe. the midsole flexes with you whilst you're running whilst still giving you ample stability on technical terrain.
Outsole: The Norvan SLs use Vibram Megagrip - this is one of the best rubbers used in outdoor footwear because it offers reliable traction on a multitude of different terrains - no matter if they're wet or dry. it is also incredibly durable - which is especially important if you plan on upping your mileage on the trails this season.
How do the Norvan SLs fit?
The Norvan's have low volume over the forefoot and a secure hold over the metatarsals for a precise fit over technical terrain. The shoe sits close in the heel cup but a have lots of width over the met-heads so the toes can splay when you're running. The shoes will fit comfortably up to an E width foot, but may give the perception of a 'narrow' fit due to the volume. If your feet fit mid'volume shoes better, then possibly have a look at the Novan LDs from Arcteryx. Getting footwear sizing right online can be tricky, so we recommend giving our Footwear Sizing Guide (found below in the Care and Advice section) a quick read.
Summary
Possibly the most clever feature of this shoe is that the weight doesn't change when they get wet. None of the shoe holds any water so you won't feel weighed down even in the worst conditions. The Norvan SLs beautifully embody the Fast and Light ethos whilst maintaining performance over even the most technical terrain.

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.
