We recommend measuring your feet with the thickest socks that you intend to wear with those shoes as this can make a big difference in how much space your are left with.
We also recommend that your wear your shoes 1-1.5cm longer than what your foot is (especially if you have rigid high arches). This is to allow for the expansion of your foot over-time. It is nevertheless recommended for everyone as your foot grows in length the more force/weight you put onto it. Through plantar pressure readings we find that the foot grows 10-50cm squared in total surface area from walking to running!
This will also vary depending on the style of shoe you want to wear as the type of material can effect the amount of volume and experienced "tightness" of the shoe.
Each brand that is listed on this website has their own measuring and size guide that we recommend you look into before purchasing, as they have their own methods of measuring.
It may be a good idea to measure your feet in the evening after you've been on them for a full day as your foot will be larger in size in the evening compared to the morning. There are two main methods;
Simply trace an outline of your foot, making sure you have your full weight on it, and measure the distance from the middle of your heel to the end of your big toe. Keep in mind that doing this will add ca 0.2-0.5cm to your actual foot size depending on the pen/pencil you use.
Use your measurement and add 0.5 – 1cm. So if your foot measures 27.5cm, the measure you want to use to compare on size charts is 28 or 28.5cm. This should be compared with the internal length of a shoe, i.e the insole / footbed.
To measure the width of your foot, measure the distance between the outer edge of the big toe to the outer edge of the little toe. Taking into account the margin of error of 0.2-0.5cm due to the tracing method.
This method is slightly more accurate as it is not affected by the tool you use to trace your foot. Measure your foot length by placing your heel lightly against a flat wall and placing something straight and solid, preferably heavy where your longest toe ends and mark that point.
Do the same procedure for the width of your foot (by placing the side of your foot against the wall) and making sure your toe's are splayed.
