Regardless of the material, toe caps for safety shoes must meet the same requirements. They are tested in a drop test (200 joules of drop energy, which is equivalent to approximately 20 kg from a drop height of one metre) and a static pressure test (15 kilonewtons). At maximum load, the residual height under the toe cap is determined and compared with a minimum requirement, depending on the shoe size. The caps used for uvex safety shoes far exceed these requirements. Plastic caps are lighter than steel caps, do not become cold as quickly and are not magnetic, and can therefore be used in areas with metal detectors or induction loops, for example.

Non-metal, penetration-resistant insoles are made of multilayer, highly tear-proof textiles, while steel insoles are made of a steel strip. Attention: Please note that the penetration resistance of this kind of footwear has been measured in the laboratory using a truncated test nail with a diameter of 4.5 mm and a force of 1,100 N. Higher forces or nails of smaller diameter can increase the risk of penetration. In such circumstances, alternative preventative measures should be considered.
Two generic types of penetration-resistant insole are currently available in PPE footwear. These are made from metallic and non-metallic materials. Both types meet the minimum requirements for penetration resistance in accordance with the standard marked on the shoe but each has different additional advantages or disadvantages, including the following:
Metal: Is less affected by the shape of the pointed object / hazard (e.g. diameter, geometry, sharpness). Due to the limitations of the shoe manufacturing process, the entire tread of the shoe is not covered.
Non-metal: May be lighter and more flexible, and covers a greater area when compared with metal but the penetration resistance may be affected more by the shape of the sharp object / hazard (e.g. diameter, geometry, sharpness).
For more information about the type of penetration-resistant insoles in your footwear, please contact the manufacturer or supplier.

The uvex multiple fit system means that in many product groups, each shoe size is available in three or four different widths. Details can be found in the product descriptions for each item. We recommend that you measure your shoe size and width using the uvex fit advisor app before purchasing uvex safety shoes. The app uses two calibrated photos to determine the measurements via your mobile and then recommends the right uvex safety shoes for the application area you have selected. Alternatively, you can follow the instructions on our website here, measure your feet yourself and then find the uvex shoe size you need in the uvex Mondopoint chart, which is published in our catalogue and on our website.
Determining shoe size and width requires the wearer's foot to be precisely measured, including the exact length and breadth in millimetres.

It is not generally possible to give an expiration date due to a variety of factors. As a guide, you should assume five to eight years from the date of production. The service life depends on the degree of wear, where the shoe will be worn and external factors such as heat, cold, moisture, UV radiation, chemical substances and mechanical loads.
The shoes must be checked for externally visible damage before each wear and replaced if any damage is present e.g. integrity of outer shoe material and outsole, sufficient tread, functionality of fasteners (where applicable). Footwear that is no longer usable must be disposed of as either industrial or household waste. Footwear must be stored and transported properly, preferably in cardboard packaging in a dry environment. Footwear should not be stored at temperatures over 25°C or in environments with humidity levels of over 70%. The month and year of production can be found on the tongue label of the footwear in the format month/year.
