Affenzahn Shoe Size Advisor

What is important when measuring children's feet? How do I know which shoe size is right for my child? The Affenzahn size advice for our children's shoes can help you find the right fitting shoes.

The shoe size advice check as a shortcut:

  1. Is the printout correct?
    Please make sure that it is printed on the scale 100% so that the correct ratio is shown.
  2. Fold the card along the purple line and place the printout against the wall.
  3. Position your heel at the bottom line!
  4. If your longest toe touches the blue dotted line, your new shoe fits perfectly!

Step by step through our Affenzahn Size Advisor

In our Affenzahn Size Advisor, you'll find the "Heel-to-toe length" in the chart next to the shoe size. To print out the correct size advice, you can refer to your child's current shoe size.

The Affenzahn Size Advisor will help you find the perfect size for our shoes. To ensure that this works as simply and accurately as possible, we have a "footprint" for each shoe length to print out. Print this template (please pay attention to the scale/print size 100%) in the shoe size your child is currently wearing. It is best to print out the current shoe size as well as the smaller and larger template.

Now you fold the sheet at the lower dotted line and place it with this side on a wall (the heel points to the wall). Then your child stands with both feet (not barefoot, but with socks) on the printout, so that the heels touch the wall. Now you can see exactly how the foot would stand in our shoe. It is, so to speak, the look into a “sliced open” shoe.

Three colors and two lines

On this footprint you now see three colors and two lines. The lowest line, seen from the heel, sets the "optimal" length. If now one of the longest toes covers the lowest line (the blue dotted line), then the shoe size is exactly correct. This way the foot would have enough space to grow to the next line (6 mm) without the shoe becoming too small.

However, when the feet grow above the second line (the line between the blue and purple area), it is time to change to a larger shoe size. Because there should always be a 6 mm space in each shoe to unroll, so that the toes do not touch the front of the shoe/toe cap and the toes are squeezed by it.

What do I do if my child is exactly between two sizes?

If your child falls between two sizes, we recommend that you take the smaller size rather than the larger one, otherwise the risk of tripping would be too high. (Our shoes are broad and wide in the toe box, so the toes have much more room than in a conventional shoe). Since the width also increases with a longer shoe length, this is often also another scale to find out the right size.

Check your kids shoe size monthly

In addition, we would recommend that you check monthly whether anything has changed in the foot length and thus possibly also in the shoe size, because children's feet usually do not grow evenly or regularly. Sometimes children's feet can also skip a shoe size, which is why we cannot directly assume that it will simply be the next larger size, but perhaps already 2 sizes larger.

As you can see, there are no fixed indications here, as every foot and every child develops differently. Therefore, it is even better to measure and test regularly so that your child does not wear shoes that are too small where the feet cannot develop and grow healthily.


What does the blue area on the template mean? This area is 6 mm long and represents the space for your feet to grow. The growth allowance ensures that the shoes offer enough space for a healthy development of the feet.

What does the purple area on the size advisor mean? This area indicates the 6 mm space for your feet to unroll. This space should at least be present in every shoe so that the children's toes are not permanently compressed and bump against the front.
