Light and springy for tempo and long runs; a good share get heel slip and Achilles blisters.

PositiveLoves the Mach X 2 and is buying a second pair; it is a much faster, speed-oriented shoe compared with a daily trainer like the Mach 6.

PositiveFinds the Mach X 2 much better than the Boston 12 at faster paces, with more forefoot cushioning and a rocker that suits their forefoot strike.

Positive'Brilliant, but watch out for that heel': bouncy, fast and fun for any training run, maybe even racing. The lightweight upper's heel design will rub some runners and is the shoe's only real downside.

MixedA 3:20 marathoner loved the Mach X 2's fast midsole but returned it over heel issues, preferring the Cielo X1.
The Mach X 2 is a light, springy shoe that most runners enjoy for tempo and long runs. The main problem is the heel and ankle collar, which gives heel slip and Achilles blisters to a good share of wearers, though others have no issues. A few mention outsole wear.
