In 2008, our flagship Support shoe introduced BioMoGo to the world. In 2009, the Trance™ 9 unveils the new-and-improved Progressive Diagonal Rollbar (PDRB®), delivering unsurpassed cushioning and effortless, but supportive, heel-to-toe transition. Did we mention plush? You’ll feel so much premium plushness in these puppies, you may never want to take them off!
