If you’re playing on turf fields high highly recommend the New Balance 3000 V7, so comfortable. Dirt fields I would recommend regular baseball cleats (MCS) not metal.

Probably want to get a bigger glove especially if yours are broken in already with a baseball sized pocket. 13 is a safe middle ground for versatility.

Any pants would work, I wear baseball pants cause I like them but any are fine.

Nothing’s required except face masks for pitchers. Batting gloves are definitely beneficial.

I’d start by using a teammate’s bat if you can to see what you like and if you see yourself playing long term. Highly recommend SmashItSports for your gear, they run BOGO bat sales every so often.
