In general, all safety shoes are produced according to the specifications of DIN EN ISO 20345. There is no requirement/test for the ESD standard in the norm. Only the antistatic area for safety shoes is deﬁned here.
In principle, ESD shoes have the same safety features as shoes without an ESD symbol. The shoe manufacturer only guarantees the contact resistance deﬁned above. The safety-relevant features are identical for both groups of shoes so that, for example, electricians must also wear ESD safety shoes for their normal activities. A risk assessment of the workplace must be carried out to determine whether additional protective measures have to be taken for work on live systems or components. In DGUV (German Social Accident Insurance) 112-191 for the use of foot and knee protection, the lower value of 105 ohms (0.1 MOhm) is specified as the lowest limit for the resistance of a product in order to guarantee limited protection against the passing of dangerous electrical currents through the body (shocks) in work involving up to 230 V.
