Shoe width

The circumference of the forefoot

To make sure you get a perfect-fitting shoe, the right shoe size is not enough on its own. The shoe width, which defines the circumference of the forefoot, is no less important.

Shoe width should not be confused with shoe breadth. Shoe width is calculated over the ball of the foot. The circumference of the foot is measured at its widest point, notably across the ball of your foot,   i.e. an imaginary line that runs from the first to the fifth metatarsal joints (big to small toe). The height of the instep is also taken into account when measuring the width of the foot. The circumference is then stated in terms of width and transferred to the shoe.


How do I work out my shoe width?

There is no universal table for this. Shoe width is usually indicated internationally by using letters (A - I). The letters E, F and G are used for medium shoe widths, with E indicating a narrower fit. The width G denotes a broader than average foot . If you have wider feet, we recommend trying on a shoe with a width of H. We refer to these shoes as models that offer increased comfort due to their extra width. We also offer certain models for men with particularly wide feet, these shoes are marked with a width of K.


How can I find out the correct shoe width for me?

You can tell that you have chosen the correct shoe width by checking if the widest part of your foot (around the ball of your feet) fits in the shoe well without you having to squeeze it in. If the shoe is too wide, the foot will slide forward and the heel will lift out of the shoe.

This could lead to blistering and also damage the shoe. If the shoe is not wide enough, the shoes will quickly stretch and may become damaged in no time.


What role does the material of the shoe play?

Having the correct shoe width and the size are important in terms of guaranteeing the perfect fit. This optimises comfort and makes your high-quality Sioux shoes more durable. These ideal features of the shoe are rounded off through the use of high-quality leather. Natural leather is capable of optimally adapting to the changes to the foot during the day (the foot is often slightly larger in the evening than in the morning) and also of maintaining the ideal width in hot and moist conditions due to the fact that this material expands in sync with the foot.

It is not only the correct shoe size (i.e. length), but also the correct shoe width that determines the comfort of a shoe. Find out how to measure your own shoe width here.


One of the major uncertainties when it comes to buying shoes is the question of which shoe size is the right one to opt for. There are different shoe size systems across the world. Here are the three most relevant systems: US, UK and EU sizes (Paris point). With our shoe size table, you are guaranteed to find the perfect shoes for you.


Moving with light-footed ease came naturally to the North American Indians for millennia – and means one thing above all else for Sioux: ultimate comfort. This is the essential difference between German footwear manufacturer Sioux and other shoes. The famous moccasin feeling can only be truly felt on the feet when the craftsmanship is accomplished by hand. Sioux prides itself on offering a perfect fit and premium comfort.


As the foot performs a rolling motion when walking, it bears your weight in various areas and thus changes shape  in doing so. The hallmark of a perfect-fitting shoe is that the toes and the foot itself have enough space within the shoe throughout this rolling motion and that the heel experiences sufficient grip. When a shoe fits, the heel does not slip out of the back of the shoe, and the shoe sits so perfectly in the midfoot area that the foot is supported – and is unable to slip forwards – hence the shoe pinching.


Statistically speaking, the average shoe size of a German man is 42 exactly, which was also the case 40 years ago. Although people are clearly getting taller, it cannot be assumed that their feet are getting longer. When talking about “shoe size”, most people understand the length of the shoe/foot, even though the term also refers to the width.


Basically, working out your shoe size is perfectly simple. To measure it, you need a sheet of paper, the correct mathematical formula, a tape measure/ruler, a pocket calculator and, of course, your feet.
