Rocker soles will do it. They saved me from hell on earth. Look and feel weird at first, are expensive, but will take all the pressure off the metatarsals, make you feel invincibly tall and able to walk for hrs, plus keep your posture awesome. Indescribably comfortable, IME.
Notable rocker-soled shoe brands:
MBT (Masai Barefoot Technology) I used these but you have to keep the sensor dry so indoors only
Skechers shape-ups
Clarks Wave Walk (still a rocker-sole but not so pronounced as above)
Ryn. (Difficult to source in UK but arguably harder wearing. Bought a size too small in width, gutted but marveled at the quality of construction.
Have also had some success with Clarks Comfort Cell but think are discontinued.
PS beware, there are plenty of fake/imitation MBTs doing the rounds on Ebay etc. Recommend looking up a stockist and go for a fitting/trial in-store if you go down that route.
