I seen in another post that someone suggested that using easy slide on your shoe is illegel, is that so? In the past I have used easy slide extensively to help me slide. I injured both my legs in the first Gulf War causing significant damage to both my knees, ankles and calves. I took about 30 pieces of shrapnel from a cluster bomb. The only way I could even consider bowling is if I was able to slide with very little resistance or it would hurt like hell or I would end up doing a belly flop into the alley. Nobody ever complained. I am not currently using easy slide now as I have purchase a new pair of Dexter SST5 with the interchangeable heals and slide pads that enable me to slide pretty well. Nonetheless, I still keep a bag of easy slide in my bag for emergencies.
