Our Verdict
Brooks Trace 4
adidas Runfalcon 6 CLOUDFOAM
The Brooks Trace 4 is a slightly better running shoe than the adidas Runfalcon 6 CLOUDFOAM. Though they're both equally stable, and neither particularly peppy nor protective, the Brooks delivers significantly more cushioning and rebound. That said, if you're looking for a shoe to handle gym work, walking, and some warm-ups and cool downs on the treadmill, there's really not much between them, so pick whichever shoe's cheapest or the design you like best.
