This time out, the adiZero Tempo sports changes to its geometry that have made it lighter and a bit faster than before. The upper is a thin layer of mesh with welded film overlays. Minimal synthetic suede and synthetic leather supports give it both a flexible and breathable character. The midsole is low-profile adiPrene, with adiPrene+ in the forefoot. In the heel, the former ForMotion cassette has been replaced with a wedge of LightStrike EVA, which serves the same purpose: smooth the touchdown and curb overpronation. Medially, Round 5 now uses the ProModerator support to add stability to the foot in lining up over the midsole. The outersole has open areas and thin rubber pads just in the highest-wear areas to save weight. The condensed version of the story: a trim-the-fat, go-fast shoe with enough protection to keep you on the roads.
Testers: “A great, lightweight shoe for shorter, faster runs, especially in hot weather. Breathes well, feels good, nicely cushioned for a light shoe. Pretty good in support and stability. I love them.”
