HOW dial fasteners MAKE EVERYDAY WORK EASIER

Everyone is familiar with traditional laces - they are tried-and-tested classics and have been a feature of many safety shoes for decades. At the same time, work requirements, technologies, and materials are constantly evolving - and with them, the possibilities for making safety shoes even more comfortable, safer, and more efficient. Modern fastening systems offer new approaches that make everyday use easier and can improve wearing comfort in the long term. 

The NITRAS FIT SYSTEM offers a modern, comfortable, and safe alternative. The twist lock allows for precise and stable adjustment of the safety shoes – without any tedious lacing. A quick twist is all it takes to ensure that the safety shoes fit snugly, securely, and comfortably. Ideal for anyone who doesn't want to waste time in their everyday work and expects maximum safety and comfort at the same time.


HOW THE NITRAS FIT SYSTEM WORKS 

The NITRAS FIT SYSTEM is characterized by its simple and reliable operation. The robust, durable components are specially designed to withstand high loads – whether on construction sites, in industry, or in warehouses.

How it works at a glance:

+ Pull & turn – for quick tightening
+ Press & turn – for a precise, secure fit
+ Release – for quick removal without effort

The coated wire ensures even pressure distribution and prevents the fastener from loosening during movement. This means that safety shoes remain optimally adjusted throughout the entire working day – without any readjustment.

It's that easy
Here you can learn step by step how the NITRAS FIT SYSTEM works.

ALL THE BENEFITS AT A GLANCE

The NITRAS FIT SYSTEM offers a number of advantages that are immediately noticeable in everyday use. The twist lock increases safety, as the fastener cannot be accidentally loosened and there are no loose laces to trip over. At the same time, the safety shoes can be precisely adjusted in just a few simple steps – quickly, easily, and reliably. 

The even pressure distribution ensures a comfortable, pressure-free fit, while the robust, durable materials can withstand even heavy loads. This saves users valuable time, especially when putting on and taking off the shoes frequently or during shift changes. Overall, the NITRAS FIT SYSTEM ensures greater safety, more comfort, and significantly more efficiency in everyday work.

FIT SYSTEM 711 AND 712 – IDENTIFYING THE RIGHT MODEL

To ensure that the NITRAS FIT SYSTEM functions optimally, it is important to select the correct model for the respective safety shoes. 

Our system is available in two versions – 711 // FIT SYSTEM and 712 // FIT SYSTEM. Both models are specially designed for specific safety shoe models. Only the right system guarantees perfect functionality, a secure hold, and the full performance of the twist lock. When purchasing or replacing the system, always pay attention to the pictogram on the respective safety shoe.
