I am excited to try these! I've heard great reviews from people who attended bowl expo. I have Dexter SST 6's currently. I avoided the 8's because of issues I saw from several bowlers. Can't wait to try these.

I just tried out my new TPUs.  I've used SST8s, and most recently 3G Pro Tour Ultras.

The TPUs were not a big change from the 3Gs, so I got used to them quickly.  Going from the SST8s to 3Gs threw me off for a couple weeks because of the weight, flexibility, and height differences - with the SST8s higher off the ground.

The SST8s were the heaviest/stiffest, 3Gs lightest/most flexible, The TPUs are in between... but not far off from the 3Gs.

I like the TPU's insoles.  I put orthotics in my other shoes, but these "Ortholites" feel pretty good out of the box... so I don't think I'll be changing them.

The TPU is a nice looking shoe, appears well made with sturdy materials - although I prefer the color scheme of the Stealth.  The trim is darker blue than the photos (probably because of light source during photo), which I prefer.

The 3Gs are a favorite shoe, the TPU is now my other favorite shoe.  I think the TPU's sole/heel system is functionally better, the factory insole is better, and the overall construction is sturdier.  I prefer the 3G's kangaroo leather, and they feel a bit more comfortable (with an aftermarket orthotic insole) - but the trade-off is less sturdy construction and the push off sole is not interchangeable.  My 3Gs have held up well enough, with occasional need for super glue (no big deal), but I've worn out the push off sole... and decided to try something new.

These TPUs are very good - I took a chance with a new, unknown product, and am not disappointed.  The sizing is accurate.  Brunswick's marketing is accurate... they feel like they're about broken-in already, and their shape/cushioning is good like they claim.  I appreciate it when companies do not rely on "hype" to market their products... and their claims are matter-of-fact.  I have a feeling that a lot of people will love these shoes.

What I'd like to see though, is a shoe that combines the best features of both the TPU and 3G Tour Ultra.

Actually, what I'd really like to see is a bowling shoe that borrows from high-end, lightweight road bike shoe construction, including a Boa-cable system instead of shoe strings.  Why would you want this?  Because it's awesome - you'd have to try it to see why.  Ever been late to practice and you're in a hurry to get your shoes on?  Never again!

I ordered a pair of the Brunswick TPU-X, daughter got the Brunswick Stealths, and my son got the Dexter SST8 white/black/gold.  Ordered them from bowlersdeals.Com and they should be delivered tomorrow!  Feeling excited!

I got my new SST8's (New Black and Gold) about a month ago but this was the first time I bowled with them due to me being underway (Marine Corps obligations, gotta love the time on ship).

Honestly at first I did not like the stiff feeling and the fact that they had me a few extra inches off of the ground. But once I started bowling in them and got used to them they were comfortable and felt like the molded around my feet. Despite my hesitations I am satisfied with my purchase of these shoes and would recommend them to anyone.

Thermal Poly Urethane.

The advice I got from the online store, per their discussion with he manufacturer, was to move the sole 1/4" back.  Upon looking at the tip, there is a very thin lip that goes around the front, and the part where my toe drags is gone.  What I have done is put a strip of the loop side of Velcro across the front of the TPU material, and if it holds, I think it will hold off or minimize further damage.  But I did try this Velcro trick with my 3g's but it came off after like 3 frames, so this remains to be seen if the glue will hold firmly enough. But other than this problem, and this problem is because of me dragging my toe, this is really a comfortable, well built shoe. 
Comfort wise, these feel better than my 3G Tour Ultras, it does feel hotter even though there are vent holes.  Lots of bells and whistles...extra soles, heel, accessory bag, and shoe boot.  Oh yeah, and an extra pair of blue laces. 
If the Velcro holds, then I'll be all good, if not, the quest continues.
