Will arch supports help my hurt foot?

I've been boxing now since may, and I'd finally gotten my footwork down, problem is as soon started to perfect it, the ball of my right foot, started to hurt, where I can't put any weight or pressure on it, I can't shadow box, jump rope, or most importantly run, I have been limping for the past 2 weeks, I have tried, Dr shoals, ball cushions, changed insoles, soaked in epson salt, ibuprofen nothing seems to help, I was wondering if arch supporters in my shoes would help, granted I have flat feet, If anyone has success using them with or without Flat feet, or know of any other remedies please tell me, thank your in advance
