Do they actually prevent calluses? I had stopped lifting for a while (~1 year) and started up again recently. Since then, I've been getting some crazy calluses.

Just a little background about me...

Butterfly 55-60 dumbbells
Curl 25-30 dumbbells
etc.

So, I'm considering buying some lifting gloves. Besides the obvious hand callus issue, is there anything else that gloves are good for/help with? Should I even be considering getting them? Thanks.
