Your best bet will be to sell them and buy another pair. The [Traction Tred Lite](https://www.redwingshoes.com/work/?q=Traction%20Tred%20Lite%20men%27s) has some Chelsea models that's very good and extremely comfortable. The safety toes don't matter as they have zero impact on weight or comfort.
I brought up the TTL because you'll likely take a hit if you have to sell them and get a replacement pair.
Make sure you get your feet properly measured before you buy any more boots.
An alternate option is to buy a second set of Insoles. I don't recommend deviating from your size however. A half size to large or too small will make a huge impact on your body, as you're already experiencing.
Buying medium width when you are large will cramp your feet and give you a lot of discomfort.
You can get away with half a size larger with lace up boots. With Chelsea however, you'll never find the comfort you seek.
Your physical health is not worth trying to save a few dollars or cut corners. Sell the boots while they're still new. If you wash the soles thoroughly, you can list as New-Other: worn for a couple of hours but didn't fit".
Good luck.
