Received my new white/black TPU-X's on Friday. Sad to report that after ten games the right front toe shield started to wear down exposing the front lip of the rubber pad which is attached to the sole of the shoe. This is exactly what happened to my original blue/black pair that I purchased a year ago.
Thanks for the frank observations.
I bowl with a few guys who use TPU-X's. To a person they rave about the comfort of the shoes. I recently tried on a pair of Stealth's, which are essentially a lower end version of the TPU-X, and was surprised how comfortable they are out of the box. I can get them at an incredible price, so they're definitely worth the look.
From what I've seen of the TPU-X, and in examining the Stealth, I'm not convinced the shoes can hold up to more extreme use.
I bowl a lot (20-30 games a week) and I put a lot of pressure on my pivot toe. I need a shoe that hold up to serious use, so in the end, I'm sticking with my Dexter 9s. They're more industrial strength, even if they didn't have the initial slipper like comfort out of the box.
