I would sort of disagree. If you're wearing out shoes fast you might want to look into your form. I say that from a long-term perspective - if you're wrecking shoes (even lightweight shoes) over time I can't imagine that would be very good for your legs.
I get easily over 1000 miles/pair, and tend to run in lighter shoes. I'm 5'8" 175lbs, do about 75% of my miles on pavement. I did about 40% of my miles this year in a pair of the Brooks Burn, their lightweight shoe before the Pure Project series. Just the other day I looked back to see when I bought these Burns, it was fall 2007, which tells me I probably have about 1200 miles on them. Before the Burn my main shoe was the Brooks Glycerin, which I would guess I got about 1500 miles out of. Even back in the day, race flats, between races and workouts I got at least 300 miles out of them (Nike Sock Racer, Nike Duelist, Asics Gel racer, Reebok Racer X).
Back to the OP...I can think of 3 truly awful pairs of shoes I ran in...Nike Shox (can't remember the model), Asics Nimbus, Loco XPresso. I got all 3 as demos or part of a trial so no harm no foul, but they were all bad in their own way. The Nikes were the stiffest running shoes I've ever seen. Ran about 25 miles in them and hated every step. The Asics Nimbus, was an early model, way too heavy and clunky. Something about the way that sole was built I rolled my ankle more than once in about 50 miles of training. The Locos I really wanted to like, would love to see a little company like that make it, but the pair I got the heel wore out incredibly fast. I guess it's hard to classify them as "worst" because they felt good on my feet, but I would say "very disappointing" based on how fast they wore out.
