In the midst of the hustle and bustle with children, it’s convenient whenever things can get done quickly – like putting on their shoes, for example. This is where the BOA fastener comes in: A simple turning motion allows them to be put on and taken off quickly and ensures a firm hold and robust weather resistance. Find out in this guide what makes BOA fasteners so special and step-by-step instructions on how to repair BOA shoes for children.

BOA® Fit System

The BOA® Fit System is an ingenious dial system from BOA Technology Inc that laces children’s shoes easily and securely with just one turning motion. This precise adjustable system offers a custom-fit fastening option for shoes. It consists of the so-called “dial”, which is turned to tighten or loosen the heavy-duty lace, as well as a lace guide.

Opening and closing the BOA fastener

To open the BOA dial, you simply pull it upwards. To close it, push it downwards and turn it clockwise until the shoe is securely fastened.

BOA fastener for children’s shoes

The BOA system for children’s shoes is very popular because it is an advanced system that is revolutionising the usual method for tying shoes. Instead of tying loops, the dial makes it easy for you and your child to fasten their shoes.



Other advantages of the BOA fastener for children’s shoes:


  • Easy to use: Children can easily put on and take off their BOA shoes themselves. A quick turn of the dial – it’s even possible just using one hand.
  • Precise adjustment: The system allows the shoes to be adjusted with millimetre precision. The lace can be quickly tightened or loosened for a perfect fit.
  • Robust and weather-resistant: Unlike conventional laces, BOA fasteners are very robust and weather-resistant. They don’t expand, even in wet weather.
  • Favourite among children: The combination of a cool design and great functionality makes the BOA fastener especially popular with older children. It provides a stylish alternative to conventional laces.
  • Saves time: The BOA fastener is particularly ideal for impatient kids. The shoes are put on in no time – and children are instantly ready for new adventures.
  • Versatile use: At superfit, BOA fasteners are primarily used in athletic sneakers and functional winter boots, providing a broad selection for various activities.

BOA fastener variants for children’s shoes

In most cases, an L6 fastener (low-power 6th generation) is integrated directly in the tongue of children’s shoes. This dial is notable for its excellent grip, is easy to operate even when wearing gloves, and is extremely durable. This makes it the ideal choice for children’s shoes.

Repairing the BOA fastener

Frequent use of the BOA Fit fastener may result in signs of wear and tear that necessitate a repair. The lace could snap or the cap of the dial could be lost. You can obtain a free repair kit both directly from the BOA website and from specialised retailers. This allows you to conveniently repair the BOA dial yourself as long as the damage is to the dial or the lace. However, please note that damage to other parts of the shoe, such as seams, sole, outer material, and tread, cannot be repaired with this set.
