I just bought a pair of Archmolds Maximum insoles (www.archmolds.com). They are a heat moldable, custom insole and they are unbelievable. I have tried them in 2 games so far, and my feet feel so much better and I am in complete control. These insoles also have Nano-Silver built in, so they help kill bacteria and avoid smelly feet from sweat. I highly recommend these insoles for all badminton players.
