Safety-relevant features which have to be considered according to BGR 191:

If you use any insole other than the standard checked one, the following parameters which have to be fulfilled according to EN ISO 20345 could change:

  1. The space below the toe protection cap (e.g. if the used insock is thicker than the standard one)
  2. The electronic flow resistance and therefore the results of the antistatic respectively the ESD efficiency
  3. The energy absorption of the seat region

When adjusting safety shoes orthopedically, the following parameters which have to be fulfilled according to EN ISO 20345 could change:

  1. The sole tearing force
  2. b) The electronic flow resistance and therefore the results of the antistatic respectively the ESD efficiency
  3. c) The energy absorption of the seat region

After the orthopedic modification, the parameters still have to comply with EN ISO 20345.
