I bought these for the county fair to run some power cords in a busy food court area. They held up well to both foot traffic and the occasional truck/ATV traffic. They started to separate and move about the gravel food court a bit because they weren't secured, and checking them once a day was enough to straighten them out to keep them in for a week to keep in line. I've also used them on a flat floor and they worked much better (as you would expect).
