Macca,
It was my first run for over 2 years. They felt heavy at the beginning but not so much at the end. I think most shoe brands with these features would have felt heavy on me. Give it a month when I've worn them in a little and then....
Btw they weigh 383g it's not exactly heavy!!
On paper it may appear that way compared to some other brands /shoe types i.e. racing shoes at 150-200g
It depends on what you want out of the shoe. I now need a stability shoe, previously prone to injury I'm happy for the extra cushioning(gel in forefoot and heel) not forgetting the revolutionary SPeva???
These will get me started and I'll see what's out there when it comes to renewal time.
Get yourself assessed and base your purchase on your particular circumstances (i.e. gait, weight, road surface...)
Cheers
H
