“Is massage or chiropractor better for foot pain?”

It's a personal choice. And of course, it depends. On the skill of the masseur and the chiropractor.

You have to know what causes your foot pain, structure problem, muscle or tendon, or systemic problem.

They can both be very effective.

It really depends on several factors - the training and experience of the practitioner, the etiology of your foot pain, and how you are caring for it yourself. If you go the massage route, my personal preference is to find someone experienced in myofascial work and visceral manipulation. the work is much more specific and gentle. If the foot pain is soft tissue related, that would be the best place to start. They will address your whole body. The foot pain may be a downstream effect from upper body restrictions and imbalances in posture or uneven gait, for example. I do visceral manipulation in my practice. I once treated a patient for foot pain. The only assessment I made with my palpation was liver restriction. Once I addressed that, the foot pain resolved. You just never know...
If the foot pain is related to skeletal misalignment, then chiropractor is where you could begin. Other tools to consider - craniosacral therapy, acupuncture, hydrotherapy, changing shoes, orthotics. If persists, make sure to get imaging.
