What runners say

“It's a great shoe for forefoot strikers; it has very good cushion up front but I could imagine it would be too hard in the heel for heel strikers.”

Pros

  • Comfort averages 4.7 out of 5 and durability 4.4 across ten reviews.
  • Averaging 7.9 oz across the men's and women's builds, it is lighter than the 8.9 oz median for daily trainers on sale, and three reviewers call it a more durable Kinvara.
  • Two reviewers praise the roomy forefoot with a secure heel and midfoot.

Cons

  • Value averages 3.9 out of 5, the lowest of its dimensions, and one reviewer calls it expensive.
  • Two reviewers size up half a size because it runs short.
  • One reviewer's foot slides in the stretchy upper on uneven ground, and another finds it clunky for speed.

So far, great. Maintaining the lightweight feel of a Kinvara while also feeling very durable makes me feel better about the overall lifetime and wear of the shoe.

Overall

As with most saucony shoes, had to buy half size bigger than other brands. But I like the fit, space for toes to spread in forefoot. stretchy upper feels nice, but sometimes feels like it doesn't hold midfoot tight enough on trails/uneven surfaces, and foot slides side to side. Cushioning is great.
