Blog · Coach – Nick Harris-Fry · summarized
PositiveNick Harris-Fry found it a comfortable, light and versatile daily trainer with enough pop for fast finishes. It runs narrow, is less bouncy than the Rebel v4 and lacks the propulsion of a plate for long speed work.
Blog · Treeline Review · summarized
PositiveLight, responsive and great for speed work, almost like a cushioned racing flat. One tester was comfortable on long runs. Another tester (hip arthritis) found the cushion too thin past 2-3 miles, and the exposed foam is a durability worry.
Blog · Stefan läuft – Stefan · summarized
PositiveStefan calls it his favorite road shoe, versatile from roughly 6:00/km long runs to 3:50/km intervals, with no blisters and still not “done” at 1,000 km. It is less comfortable than a Clifton and somewhat slippery on wet or icy ground.

PositiveAfter three runs, finds the Mach 6 a versatile all-rounder and one of the fastest non-plated shoes they've run in, nearly preferring it to the Endorphin Speed 3 for picking up the pace.

PositiveWith 250 km on both, calls the Mach 6 the clear winner over the Rebel v4: heavier but much more fun, faster, responsive and comfortable, while the Rebel is hit and miss.
Most runners find the Mach 6 light, responsive and fun for daily and tempo runs, and many get several hundred kilometres from it. A narrow fit is the main complaint, with many buying the wide version or sizing up, and a few report the foam or outsole wearing out early.
