Is there a relation between heaviness of sweaty feet and the effect of PediSpray?
No there isn’t. There are so many reasons, which all are of some importance to the effect of PediSpray, that you can’t predict a certain outcome. Environment, type of weather (hot or cold, dry air or the opposite of it), type of shoes (open, closed, type of leather, thickness, type of sole, using inlayers or not) type of feet (more or less horny skin), if you are wearing socks or not, etcetera. It’s also of importance what you are doing daily. If you are working as a waitress in a restaurant, being a taxi driver or website builder behind a desk. That’s a great difference. But one thing can be said. It just works. That’s a fact.
