Does Anyone Know if Compression Would Help Reduce Cankles?

All this talk about cankles on TV lately has me really concerned about cankles. And its not just me. It seems like everyone at my gym feels the same way.

I have always been prone to water retention my whole life, and I was wondering if these compression garments or ones similar to it would help to reduce swelling and water weight for me, or if I would just be making myself extremely uncomfortable for no reason.

Could someone please help me solve this? Please and thank you.
