Our Verdict
ASICS SUPERBLAST 3
Speedland RX:PNW
The ASICS Superblast 3 is a better shoe than the Speedland RX:PNW overall. Both are deeply cushioned performance shoes that can handle regular mileage through long-distance racing, but the ASICS offers significantly better shock absorption, a smoother transition through stride, and a lighter build without using a plate. It's also less expensive. However, wider-footed runners may prefer the Speedland's more accommodating fit.
