This is my take on slide issues. People tend to slide like they walk. What i mean is if you walk heel first then you will tend to slide heel first and no shoe adjustment will cure this. The only way to fix this is to recognize how you walk and how you need to walk.
I agree most sliding issues are due to technique, or lack there of. While every step up until the slide should be your typical heel-toe step, but the slide should be toe first to promote the slide, with the heel coming down a split second later. Coming down heel first just ends up making you stop short, and then that causes other issues in the physical game.
Most high dollar shoes have an elavated heel pad and that will only make it harder to slide if the pad of the slide foot (toe area) isn't absorbing the majority of the slide first.
If by high dollar you mean Etonics, I'd have to agree. But all of the Dexter or 3G shoes I've seen the heel is similar to the typical universal shoe. Etonics tend to have that huge heel though.
If you want to check and see if this may be your problem then that is simple. Put some powder on your heel and throw a normal shot. If you slip then you now know why. Be careful...
I used to bowl in a league with a bowler that did that all the time. His whole slide was done leaning back on the heel. He would have the Power Slide sitting under his chair, normally the back table on the carpet and would step all in it and trace it up to and on the approaches. One night bowling against this team, my brother who was on my team literally fell backwards 3 times during the first game. Finally the president reluctantly made the bowler stop using it after my brother complained a couple times and I finally went down and got into it with the president. The offending bowler complained he couldn't slide without it. I say the president was reluctant, because he would selectively enforce rules to try to stay at the top of the standings, and both seasons in that league we were near the top with them. I seen him do something similar things to other teams that were just as competitive.
My brand new bowling shoes will not slide at all. The shoe has almost like a carpet like texture on the bottom. I took a wire brush to the shoe and a bunch of fabric fell off of the shoe but the shoe still has a fabric like texture on the slide. What is this and is there any possible way to fix the shoe?
What shoes do you have? Even with good slide technique some shoes could be problematic. Some shoes the heels need broken in too. Walk on carpet with them dragging the heel a little, just be careful not to step on anything that could get on the sole. Preferably do it at home. It helps scuff the heel up and makes the heel where it won't grab immediately.
