My hand numbness was not caused by my gloves, it was definitely a hand position/handlebar reach/locked elbows issue. I had mountain bike handlebars and switched to trekking bars, and while I still have occasional tingling, it's is SO much better than it was. I would look into those items because it could be a really simple adjustment you need to do to help get yourself off your hands so much.
Good luck!
