The bell has rung and it's time to expel old school shcool shoes! Out with the chunky, heavy and oppressive old and in with the light, flexible and fun new school kicks by PaperKrane.

These Biro Lace-up style shoes with their buttery soft black leather uppers, elastic laces and rubber soles, are so effortless to wear due to their slip on style (laces can simply be pulled tight or loosened, so no need to tie laces!), and will have your little students feeling comfortable all day!

It's time to put other school shoes in detention and to give these PaperKrane school kicks a go because they are top of the class when it comes to foot health and comfort!


Please be advised, wearing shoes too large is not great for little feet, so do not size up too much. 


  • FLEXI - Natural rubber sole that packs a punch in the flex department 
  • Lovely pebbled black napa leather uppers, with pig skin/microsuede lining. 
  • Stretchy elastic laces for easy slip on. 
  • As with any new shoe we recommend you continue to wear socks with them while they are being worn in. The leather and shoe will soften over time, but it's not unusual for brand new pairs to feel a little tight or stiff to start with. Especially if your child is used to our fabric pairs.

  • To make cleaning your PKs easier we suggest treating with a waterproof stain protector first, for school a leather conditioner that also contains a polish is best. As that will allow you to regularly touch up any scuffs that occur on the playground. 
  • FLEXI SOLES - Spot clean or wet wipe - Do not machine wash. 
  • Do not leave to soak in water to avoid any damage to the leather.
  • Brush or wipe the soles to clean. 


Colours may vary from screen to screen. As with any item made from leather, natural markings and creases may be found in the outer material, and wear and tear from regular use will be part of the normal life of this item, every line, scuff, or mark tells the story of an adventure your little one has been on.

Our size charts are specific to our shoes, and may differ from your usual footwear so we always recommend you measure before ordering.

If needing more detailed instructions on "How to Measure" please scroll down below the size charts.





Stand with feet on a piece of paper, and mark where the end of the longest toe/s are, and middle point of the back of the heel. 

Use a ruler to measure between those two points. (Use your longest foot measurement - Look at the "BEST FIT" column to see where the foot fits best.

* If closer to the end of the "BEST FIT" measurements then the next size up will be a better choice.

For most comfortable fit, aim to have up to 7-12mm of extra space in the shoe.  

If socks will be worn in the shoes, pop on the socks and then measure in the same manner. 

We include a width measurement across the ball of the shoe, this is a measurement of the FLATTEST part of the sole, so there is always more available space than stated, as the sole curves out and up giving your feet more room to spread. 

We also have a natural rubber sole that is able to flex with a foot, which helps accomodate feet that have more width. 

While the available length measurements are the same across all styles, the upper construction affects the fit and feel of the shoe.
