Ok so I got orthotics (sp?) recently and they don't fit well in my shb-98's. They're actually ok if I do running on a treadmill, but when I went for a game of doubles for the first time I found that they seemed to slip out of position which was quite uncomfortable. If I put my hand inside the shoe I can move the insole forward and back a bit. Does anybody have any suggestions on how to fix this? I can't glue them in because I have to transfer them to whatever shoes I'm wearing. Maybe I just have to go buy shoes which are slightly smaller?
