New gloves don't fit right..

I ordered the Rival rsv2 16oz gloves online without trying them on. I've used them a few times and have sweated in them pretty bad. Don't think returning them is an option. The fit is too long for me and I'm not getting adequate wrist support. I do more bag work than sparring but I got sparring gloves stupidly. I want to get bag gloves when I get more cash but am screwed for now. Anyway thought I'd share; any suggestions?

 sell them on ebay?
