In short

Runners most often mention the VIA Olympus 2's arch shape, which bothers several, though one says it faded after about 30 km.

Firm but durable with a grippy outsole, though some find it too harsh for easy days or long runs.

Comfortable trainer, though several find the ride flat or dead.
