I'm a right-handed player and for years have found that my left badminton shoe gets abraded and eventually splits always in the same place - on the instep just a bit forward of the arch. Does anyone else experience this? I am quite fast around the court and play singles as well as doubles. Some playes say it is my foot dragging on the floor but this cannot be so as the split develops about 1" above the sole level and there are no other such indications anywhere else. I wonder if it is my footwork, i.e. as I chasse my right heel sometimes unknown to me clips the inside of my left foot but I don't notice as I play. I never trip over my own feet! I would be interested to hear anyone's comments and remedies as it is costing me a lot of money in badminton shoes!
