Great for Training and Racing

With version 4 On has removed the debris-grabbing groove from the forefoot sole and made an excellent racing shoe. I've owned every version. The Cloudflow has always been lightweight responsive low-drop and fast. And every version has comfortably reached over 300 miles of street running. But that groove between the clouds would collect gravel and other debris rendering it unsuitable for racing. With version 4 the groove is gone and this is the best racing flat I have found.
