Hi, This is my 2nd pair of the Prince T10s. Overall I have no complaints, but I noticed sore feet, particularly my heels, after my 90 min hardcourt match last night. I don't remember whether this has always happened or if it's a new phenomenon. Could it be that the absorbing qualities of the shoes are worn out? I've played these shoes about once a week for 6 months. Should I look for a more cushioned shoe in my next purchase, such as the MC4?
