Verdict

The most versatile super shoe on sale. Light enough for a 5K, cushioned enough for a marathon, and the fourth generation fixed the upper problems that made the VF3 divisive.

■ Caution

Less cushioning than the Alphafly for a full marathon if you are on your feet over three and a half hours. Outsole rubber is minimal — treat wet corners with respect.
