Alright here is my problem and I need a quick fix because I have to figure it out by tomorrow cause I have a tournament on Sunday that I want to be really well in.  The past 2-3 weeks I have been bowling very poorly because I do not feel comfortable on the approach and my slide.  Currently I have dynothane shoes but they are a little customized.  I cut the triangle off the heel in the back so I can use any sole.  I also took off the lining around the sole so I can use any sole.  I have been using Dexter sole 2 and heel 2 (round reversible) for a long time now but lately I have been sliding like crazy and I do not know why.  Those are the least sliding sole and heel combination I have found and I have used everything.  I have pretty good by the book form and use my heel to brake but I cant stop sliding lately and I do not know what to do so I am hoping someone on here can tell me some ideas.  I havent changed anything in my form or approach in about a month so I know it isnt related to that.  Please shoot me anything, need to fix this.  I have had a few people watch me and my timing is still good.
