Brooks Green Silence will replace my current Adidas Adizero Adios flats for the following reasons:
- simpler design (about half as many components as in average racing flats)
- light weight (my GS size US 10.5 and my Adios size US 11 both weigh the same, ie. 225 grams)
- lower arch height (suits my feet better)
- thinner sole (GS heel/midfoot 18 and forefoot 10 mm vs Adios heel/midfoot 22 mm and forefoot 11 mm)
- lower heel-to-toe drop (8 vs 11 mm)
- asymmetric vamp & lacing system with a wrap-over tongue
- the only seriously green & fast running shoe (75% recycled shoe materials; 100% recycled laces, gillies, webbing and packaging; biodegradable midsole and collar foams; 38% less solvent in water-based glues; non-toxic colors, etc.)
Green Silence also seems to provide a tempting alternative to Brooks Racer ST, my old (ultra)marathon favorite. However it remains to be seen if GS can provide enough protection and support for longer distances.
I guess it depends on how well I can execute my two main goals for 2010:
- weight down, and
- cadence up.
"Silent steps to a greener future..." Sure thing, but the hot colors seem to scream for attention. The bold asymmetric design is a winner in my book, although it might scare traditionally minded folks.
With appropriate laces this might even be suitable for triathletes. I could certainly imagine running without socks in these in summer, whenever 100% barefoot is not an option (ie. most of the time for those who live in the city).
A more thorough review will follow after some serious training and racing this spring. Meanwhile, here's a video by The Running Couple.
Plus another review, if you'd like a second opinion :-)
