We know that finding the right shoe size can be tricky!
We’d recommend looking at the size guide which shows the approximate length of each size’s midsole in centimetres.
If you already have a hiking boot, running shoe, or training shoe that fits you well, you could measure the length of the shoe’s insole and match this with the size guide.
Alternatively, you can measure the length of your foot and add between 1 and 2cm to find the correct insole length. It is hard to be exact here, as sizing is so personal – but in hiking boots, running shoes or training shoes, we’d recommend having at least 1cm of extra space beyond the end of the longest toe to ensure comfort.

FOOTWEAR FITS (PRECISION, STANDARD OR WIDE)
Please note that these widths are intended only as a rough guide. We strongly recommend you measure the width of your feet before deciding which fit is best for you.
Depending on the type of activity you’re doing you may wish to go for a more precision fit (for racing for example). Equally you might prefer a wider fit if you are running longer distances or lifting heavy weights.

HOW TO MEASURE THE WIDTH OF YOUR FOOT
Make sure you’ve measured the length of your foot first. You’ll need this measurement to work out the correct width.
- On a hard floor, put a piece of paper against a wall.
- Stand on the paper in your socks. Wear the type of socks you’d normally wear with this type of shoe.
- Make sure the back of your heel is against the wall and that you’re placing your weight on your foot.
- Ask someone to trace a line around your foot.
- Make a mark either side of your foot, at the widest point.
- Measure the distance between the marks using the width chart below.
- It’s common for feet to be different widths, so make sure you measure both.
You should choose your width based on the measurement from your wider foot.

Shoe Fit Scale
| Fits Narrow | 1 | 2 | 3 | 4 | 5 | Fits Wide |
We have graded the fit of all our shoes from 1 to 5 to make it easy for you to find the perfect fitting shoe. All our shoes are designed with Met-Cradle technology to lock down the mid-foot for a stable hold. Where they differ is in the toe box. Grade 1 represents our closest, most precise fit. At the other end of the scale, Grade 5 has the widest fitting toe box.
We have meticulously studied the foot and its function during the gait cycle and also the interaction between the foot and the terrain. We have used this knowledge to develop our fitting scale. For technical footwear a good fit is essential to enhance your performance.
The lower the number on our scale, the narrower the fit, which ensures minimal internal movement of the foot when running fast on technical terrain. Shoes with the higher numbers on our scale will suit athletes with a wider foot and those wanting that extra comfort in the toe box. This wider toe box allows the toes to splay for increased stability when lifting heavy weights. It’s also perfect for longer runs and races when toes begin to swell.
As a rough guide, Grade 1 represents an industry B fit, while Grade 5 equates to a 2E fit in the forefoot.
