Yes – an ESD floor is part of a system for personal grounding.
“For standing operations, personnel can be grounded via a wrist strap system or by a footwear-flooring system. When a footwear-flooring system is used, personnel shall wear ESD footwear on both feet and the two following conditions shall be met:
• The total resistance of the system (from the person, through the footwear and flooring to ground) shall be less than 1,0 × 109 Ω;
• The maximum body voltage generation shall be less than 100 V.” (IEC 61340-5-1 5.3.3)
