What's the difference between a field lacrosse short stick and box lacrosse stick?

My understanding is that they're not the same. But I have no idea what the difference is.

 

I dont think any companies are still making box specific heads, so, they are mostly the same.

rules do allow box sticks to have narrower heads and deeper pockets, so, you can pinch the rails and tweak the stringing for better hold.

NLL also used to allow 40-46", but, believe they normalized it to 40-42", so, shafts are now identical.

 

Interesting, thanks
