ASICS Blazeblast vs On Cloudsoma

Blazeblast or Cloudsoma? Here’s how they compare on feel, fit, brand specs and price, from the fitting team at The Run House.

The short answer

Want plush cushion and grip for pavement, gravel and easy trails? Get the Blazeblast.

Want a light, flexible shoe for roads and light trails? Get the Cloudsoma.

Get the Blazeblast if

• You want the softer, more cushioned ride
• You want more foam underfoot (9mm more at the heel)
• Long runs are your thing
• You need a roomier fit

Get the Cloudsoma if

• You’d like a little less squish underfoot
• You’ll use it for tempo runs and workouts
• You want the lighter shoe, by about 1 oz
• You prefer a lower drop (6mm vs 8mm)

On the run

Blazeblast: The cushy door-to-trail shoe. Plush and well cushioned, like a Novablast built for gravel. Outstanding grip on pavement and gravel, with shallow lugs that suit smooth paths. Limited to easy trails.

Cloudsoma: The light, flexible multi-surface On. Light, flexible and nimble, with slightly soft, responsive Helion HF foam. The 6mm drop feels lower. Very shallow lugs suit roads and light trails.

The Cloudsoma hasn’t been lab tested by RunRepeat yet, so its feel ratings are estimated from Doctors of Running’s and Believe in the Run’s reviews (no lab test yet).

Specs side by side

Stack, drop and weight come from each brand’s own website. Numbers marked * aren’t published by the brand and come from other published specs. Weights are for the size each brand quotes. Expected life is our estimate.

Fit

Blazeblast. True to size but not for wide feet. The upper doesn’t breathe well.

Cloudsoma. True to size with a sock-like upper that starts snug and opens up. Low volume, especially in the forefoot.
