I'm really surprised, here!!!
Or I missed something.
Because the most important difference that I know of between the $50 shoes and the $150 shoes is the NON SLIDE sole. That next to the last step should be on a firm sole, not a suede sole. With a suede sole, I'm off balance, and can't be stable to get the shot off my hand.
All bowling shoes(except house shoes) used to be made in both right and left hand models. Now, only the more expensive shoes are made that way. I know of some people who wear a sneaker (only used for bowling) on their non slide foot, and if it works, I don't have a problem with it. All my family members that bowl have "handed" shoes. Period. I wouldn't let them bowl any other way.
