The answer may amaze you-- there is actually extremely little research on the subject! A fast search of clinical journals shows up almost nothing when it concerns foot size and preferences for foot worship, indicating that we don't actually understand for sure if there is a connection.
That doesn't suggest that we can't make some educated guesses. It seems sensible that people with larger feet would delight in having them worshipped more than those with smaller sized feet, merely due to the fact that there is more area to deal with! And indeed, many individuals who enjoy foot praise report that they have bigger than average feet.

People with high arches or particularly delicate feet may enjoy having them dealt with in a different way than those with large feet or flat feet. And obviously, some people just take pleasure in having their feet worshipped no matter what they look like!
If you're questioning whether people with different foot sizes have different choices when it comes to foot worship, the response is: it depends. There is no set guideline, and ultimately it depends on each person to determine what feels great to them.
