The Flow has more midsole thickness than the Brooks Connect. Look at this if you like the idea of a lower ramp and a minimal shoe, but aren't quite ready for take the ultimate "natural" plunge.
This is the Pure Project model that comes closest to a minimalist shoe, but the sole is still too cushioned to fit squarely into the minimalist category. It's natural running with a bit more cushion.
Forget the literary overreach by Brooks on the technical aspects of this shoe. The ecstasy exceeds the utility. Just wear the shoe. It's a very good update of the Glycerin line.
In contrast to the storming hordes proclaiming natural gaits and barefoot running, the Brooks Beast stands its post, on its wall. Overpronation? Not on its watch.
Brooks is not known for shoes that shout at you, but, the Green Silence is a bold and garish racing flat from an otherwise conservative - even classic - shoe company.
