How to interpret the size guide?
In our table you can see the measurements of the insoles for each size and the width (indicated in the box on the left).
To choose the ideal size:
- Measure your foot carefully
To accurately measure your foot length, place your heel against a wall and use a book or magazine to gently press against your longest toe. Mark that point and measure the distance: this is the simplest and most accurate way to obtain your true foot length.
- Compare with shoes that already fit you well
If you have comfortable shoes (preferably barefoot shoes), measure the insoles and compare them to our insole measurements. This is one of the most reliable ways to find your perfect size at Dolfie. Also, consider the type of insole: If it's flat (like Dolfie's), you can use the full measurement. If it's concave (with a small raised edge at the heel), you'll need to subtract approximately 0.4–0.5 cm from the total measurement for a proper comparison. This method is usually more reliable than measuring your feet. The length of the insole in shoes you already own that fit well is the best guide for determining your size.
- Consider the type of insole you prefer from the options we include and the fit you want: loose, recommended, or tight.
We recommend allowing a maximum difference of 1 cm between your foot measurement and the insole length, according to your preference; anything more than that may feel too loose. The boxes on the left show the length and width of the insole in centimeters.
Insole size:
If you're an expert at barefoot running and rely on insole measurements, keep in mind that the inside of the shoe is approximately 2-3 mm larger than the insole. This means the shoe will have a little extra room.
Each pair includes two removable insoles: choose between 3 mm and 8 mm according to your preferences
To choose your size correctly, the first thing you should do is look at the guide according to the insole you are going to use.
3mm insole: Comes as an extra in the box. It doesn't take up as much space in the shoe, so the fit is wider or looser (depending on the width of your foot) compared to the 8mm insole. Ideal if you're looking for a more barefoot feel.
8mm insole: Comes pre-installed inside the shoe. It takes up more space, which may make the shoe feel tighter. Choose this option if you're transitioning to barefoot running or prefer more cushioning.
Foot width:
If you have very narrow feet: If your measurement is in the middle or almost reaching the light green zone, choose a smaller size, especially if you plan to use the 3mm insole. However, if your measurement is closer to the dark zone, stick with that size.
If your foot is very wide and voluminous: If your measurement is in or near the dark green area, choose one size larger.
