I have found with gloves, especially leather gloves, they can be "customized". I get them WET. Not leave them in a bucket of water overnight wet, but wet through. Then I put them on and wear them until they dry. If they are motorcycle gloves, I ride with them on, pulling them up on my wrist frequently and as they dry, They "form fit". It is important to dry them on, so they won't shrink or get brittle. You might want to try it.
