ASA has always allowed metal spikes. Even at complexes where there is a sign that says no metal spikes allowed, metal spikes are still allowed to be used. Leagues can have their own rule on this and not allow them. But I know Norristown has always allowed them since the first year they had slow pitch in 1968.

As for safety, that's up to each league to decide on its own. I wore metal when I started. But too many tournaments and too many Sundays playing 5-6 games in the OF ... Metal spikes are not too comfortable.

The turf/trail spikes they have today are so confortable. And the traction may not be as good as metal, but it's close enough. Just explaining myself. And talking in circles as usual?
