Our Verdict

Kiprun Kipstorm Tempo

R.A.D UFO

The Kiprun Kipstorm Tempo and R.A.D UFO are both cushioned performance trainers, but the R.A.D is the livelier option. It has more bounce underfoot, while the Kiprun provides deeper protection and a more controlled ride. Get the R.A.D if you want a more energetic trainer; get the Kiprun if cushioning matters more.
