No footwear is worn so long and frequently as safety shoes. In industry, trade or on the building site, safety footwear is worn for several hours every day. The main thing for safety footwear that is used for several hours every day is a proper fit! If they are too loose or too tight, they just become an additional burden for the wearer. If blisters, inflammations or chronic pressure points develop they have an effect on well-being. Ill-fitting footwear often leads to incorrect posture that can in turn cause permanent complaints such as knee problems or backache. The consequences: The performance and concentration of the shoe wearer decrease – while the risk of accidents increases. This whitepaper aims to examine the importance of properly fitting safety footwear in the workplace. We will examine the potential risks and dangers associated with ill-fitting safety footwear. Based on several studies we will make it clear how important it is for workers to have properly fitting footwear at work, and the personal and financial costs if this is not the case. The wrong footwear can lead to severe consequences in the long run – for workers and employers alike.
