Many bowlers underestimate the importance of using high quality bowling shoes.
They can make a huge difference in helping your game. Dexter and Linds make the best bowling shoes. If you have trouble sliding buy a red slide sole that Dexter sells and some velcro self-sticking faserner. Cut both the red slide sole and velcro self sticking faserner the same size as your rubber heel on the slide shoe. Paste the velcro faserner on the rubber heal and then place the red slide sole over the velcro faserner.
