The announcement of an update to or expansion of an existing popular product often elicits a mix of optimism and skepticism from those of us who track such things.
The upside is the feeling of, hey, this new thing might be even better than that thing we love. Meanwhile the dark side thinking is more like, did they just slap on a fresh coat of paint and jack up the price?

Thankfully the latest news from Teva appears to carry more of the former than the latter.
Building on the success of its popular Aventrail Trail Running Sandal ($145), the brand has introduced two new varieties.
What you get with the new sandal is one that is nearly 32 percent lighter than the original. That weight savings is borderline insane.
One beefs it up into a full-on shoe for $160, which makes all the sense in the world. But I’m more excited about the other variant.
The new Aventrail R2T (Road to Trail) is a leaner, meaner take on the original. And if you can even believe it, it costs $25 less.
