I have arthritis in the small bones of my feet and finally had to have a fusion of one of the metatarsals and the adjoining cuneiform bone in the right foot. Not a surgery I want to repeat on the left foot. No bunions however. I love Skechers slip-ons but for anything but short walks I wear lace up athletic shoes with custom orthotics plus a carbon plate under the orthotic on the left foot. It reduces flexion of the bones.
However, I still have some pain from lack of cushioning so I’ve bought various products from https://zentoes.com/ They carry gel cushions that stick to the ball of my foot plus toe and bunion separators. Check them out to see if anything they have might help with cushioning and protecting your feet.
Hope this helps in your situation!
