Anyway, you now own a perfectly fine pair of day hikers. The Vasque Zephyrs ($135 for non-Gore-Tex version, $160 with Gore-Tex; www.vasque.com) are perfectly good shoes, but even Vasque doesn't tout them as anything more than a boot for light and fast overnightsmeaning loads of 25 pounds or less. Depending on how heavy you are, you could be way under-booted. Vasque's "classic" backpacking boot is the Sundowner ($195), and I don't even regard that as a particularly heavy-duty boot. But fine for loads such as you describe, on rugged trails or even off-trail.
Other good boots to take a look at would include Montrail's Blue Ridge GTS ($175; www.montrail.com) or Raichle's Mountain Peak XT GTX ($200; www.raichle.com). I think that Gore-Tex liners have become something of a plague in footwearsometimes useful, often notso another alternative is the rather pricey but extremely good Scarpa Delta M3 ($230; www.scarpa-us.com).
What to do with the Zephyrs? You'll use them in time, so maybe hang onto them. Or go back to the store, make a fuss, and trade them in. Or sell them on eBay. But they are NOT the boot for you.
