Is there an end-of-use date for safety footwear?

The footwear must be transported and stored correctly, in its box and in dry environments.
The maximum storage period of footwear is 3 years from the production date (shown on the internal label of footwear in month/year format), provided that the temperature does not exceed 25°C and 70% humidity.
The useful life of footwear from the beginning of use is on average 18 months, but can be influenced by the frequency of use and external wear factors that can reduce its durability
