How the plus12 works

Place plus12 by the side of the foot, so that the red arrow is a bit longer than the big toe. Then stand your child barefoot or in close-fitting socks on the plus12 .

Helpful hint: Leave the tape measure sticking out under the longest toe. Slightly lift the child’s foot, then press it lightly onto the red arrow until it reaches the end.

Read the millimeter* gauge on the back of the tape measure (that is the foot length including 12 mm extra space).

Now you already have the correct inner length for the right fitting shoe!

Insert the plus12 into the shoe until the red arrow touches the point of the shoe. If you have a problem when putting the instrument into the shoe (the red arrow does not reach the end of the toe area) it means that the toecap of the shoe is too low.

Read the millimeter gauge on the back of the tape measure^*.

So what size is this shoe, anyway? Our research has shown that most children?s shoes are misleadingly (Link to our study, abstract in english) . A shoe labeled EU size 30 (UK 11.5) is usually only a size 28 (UK size 10) in length. This is why we recommend measuring the inside length in millimeter. If you want to convert the length to size, please see www.kidsfeet.info/shoesize.

^* May vary slightly.

If the plus12 foot measurement is the same as the shoe measurement, then the shoe fits, and allows the necessary 12 mm of extra space inside. For example, if the foot measures 180 mm on the plus12, then the inside of the shoe should also be 180 mm. New shoes can leave a bit more room for growing, but not more than 17mm.
For example, if the foot measures 180 mm, then the inside of the shoe should not be longer than 185 mm.
