Our Verdict
ASICS MAGIC SPEED 5
Skechers Aero Razor
The ASICS MAGIC SPEED 5 and Skechers Aero Razor are both lightweight plated trainers built for faster running, but the ASICS is more suited to shorter efforts, with a carbon-fiber plate and a much stiffer rocker, giving it a snappier feel for 5K and 10K efforts. The Skechers is slightly lighter, more cushioned, and more forgiving underfoot, with better protection through the forefoot over longer runs.
