In reply to bowls:
Sportivas fit me like a glove. Sportiva rock boots, trangos, nepals and spantiks all used on a regular basis by me.
When I first got the nepals towards the end of the day I'd get the exact same pain in the balls of my feet, made worse when walking down hill.
After a bit, it stopped. Whether it was my feet getting used to the boots, or the boots breaking in, or me changing my walking style, who knows?
But you're not the only one.
