Looking at new bag gloves. Im used to using old worn out gloves that were way too big for my hand at my gym. Do the insides of the gloves loosen up over time...should I get a glove that is somewhat tight? Or should I get a glove that my fingers might swim around in a bit?

my gloves are pretty tight, i think the best thing is to try them on. and remember to allow room for boxing tape/handwraps
