If you are fine with the way the half chaps are, then yes go ahead and ride in them. But if you are not happy with them, I would call the company or store. You may end up wanting to return them. If your new half chaps are the same brand as your old pair, they may have been malfunctioned, I would definitely check into it. Otherwise, if you think they're fine, go enjoy your ride!
Have a good day,
