📏 “Plus12” measuring device – Perfect children's shoe fit, scientifically based
The Plus12 is the first shoe-size- and brand-independent measuring device specifically designed to precisely measure the inner length of children's shoes – and to automatically add the ideal 12 mm allowance. Developed in collaboration with Dr. Wieland Kinz, expert in healthy children's feet.
🎯 Precise measurement – foot length & shoe inner length at a glance
- ✅ Determine foot length – measures your child's foot length and automatically adds 12 mm of extra space to allow enough room for growth
- ✅ Measure the inside length of your shoe – measures the inner length of shoes in millimeters, suitable for shoe sizes from 18 to 45
- ✅ Brand independent – delivers reliable measurements, regardless of different size definitions used by manufacturers
- ✅ Compare foot and shoe measurements – this way you can ensure that your child's shoes fit perfectly and support healthy foot development.
🔬 Scientifically sound – developed with Dr. Wieland Kinz
The Plus12 was developed in close collaboration with Dr. Wieland Kinz Developed by a renowned sports scientist and expert on children's feet, Dr. Kinz authored the first German-language publication on the topic of "Children's Feet - Children's Shoes" at the University of Salzburg. His expertise and commitment to healthy children's feet are incorporated into every Plus12 device. A must-have for all parents, who pay attention to the correct fit.
👶 Easy to use – quick & uncomplicated at home
- 1️⃣ measure foot – Place the Plus12 next to your foot, slide the measuring scale towards your foot and read the calculated value.
- 2️⃣ shoe size – Slide Plus12 into the shoe to determine the inner length in millimeters.
- 3️⃣ Compare – Compare foot and shoe measurements and ensure that the shoe fits optimally not only at the toe box but also in the heel area.
🦶 Why the right shoe size is so important
The inner length of a shoe often varies between manufacturers – a size 24 isn't the same length everywhere. With the Plus12 you can measure brand-independent and precise, instead of relying on size specifications.
For example: If your child measures 12,5 cm (including 12 mm of leeway), Plus12 recommends an inner shoe length of approximately 13,7–14 cm. This ensures that the shoes always perfectly meet the needs of your growing child.
⭐ The Plus12 – Your reliable partner for a perfect fit for children's shoes. Scientifically sound, brand-independent, and incredibly easy to use. So your child's shoes always fit perfectly.

Fit of children's shoes
The human foot takes approximately 18 years to fully develop. Of course, it grows fastest in the beginning. Therefore, you parents should check the fit of your children's shoes every 3-4 months. For POLOLO street shoes, we have always developed removable soles - as far as this was possible for the respective style. On the one hand, you can easily replace a sole (e.g. add a wool sole for the winter) and you can use it to measure the foot length and fit very well. If the imprint of the big toe is already dangerously far forward, then your child has already grown again and is due for the next shoe size. Our soles are all very flexible, especially our Barefoot collection.
POLOLO pursues the highest ecological standards
When producing our POLOLOs in Spain, we pay great attention to ecological, pollutant-free materials and workmanship throughout the entire production chain. We only use German natural leather that is vegetable tanned and certified, organic quality cotton (organic / kbA) and wool from controlled organic animal husbandry (organic / kbT). POLOLOs are allergy-friendly and therefore our leathers are naturally chrome-free.
