My league resumed yesterday after a break all summer and I woke up this morning with a pain in my heel, particularly on the bottom of my heel, that made it difficult to walk for five or ten minutes. I encountered this problem before, during last season and I think it comes from jumping and pounding down on the court, particularly while jumping to reach a deeply hit shuttle or doing a jump smash. The problem occurs regardless of which of my two pairs of badminton shoes I am wearing (ASICS gel volleyball shoes or Head racquetball shoes), and I have been using the same Sorbothane full length insert in both pairs. On some occasions I have noticed that if I stretch well after playing, particularly doing an achilles stretch, the heel pain the following morning is less, but on other nights, stretching doesn't seem to matter. Clearly the problem is the result of the application of excess force to that area of my foot, and since F=M*A, I should probably work on reducing some of that M that I have picked up in my near-middle age. I'm thinking I will be buying a gel heel pad or insert and trying that. Does anyone use one and have a recommendation for the best brand? Anyone else have similar problems and/or other suggestions for dealing with this heel problem? Thanks.
