I am not an avid bowler at all, but with my children's summer bowling passes, I figured I'd buy my own shoes and save the cost of rental each time.  For the price, I'm happy.  I ordered a bit large, thinking, "What if they run small?"  They don't!  My shoes are half a size too big, and that is my own fault.  They are pretty much true to size.  The quality of these shoes is probably not for a typical bowling fanatic, as they aren't super-duper.  They have felt-like bottoms and would probably fall apart with heavy usage.  However, I have worn mine about 10 times and not had any problems at all.  I should be able to use these for many years, as I only bowl about 5 to 10 times a year.  Over time, this will save cheap little me a bit of money and I find it more sanitary to have your own shoes than to do rentals.  I would recommend this product for someone who will use lightly to moderately.  If you use them a lot, my guess is they won't last for too many years.
