9 reasons to buy

  • The soft mesh upper of the Fastwitch 8 is one of the biggest reasons why some runners loved the comfortable feel of this shoe.
  • It is a value for the money investment, based on the comments of several reviewers.
  • It is significantly lighter than the previous model.
  • The upper gets a boost in breathability because of the large and numerous holes.
  • According to a few testers, the outsole is very grippy, even in wet conditions.
  • A handful of reviewers loved the more forgiving cushioning as it allows them to take the shoe for longer runs.
  • The lightweight support is enough for neutrals and mild over pronators to enjoy.
  • There is substantially more reflective details in this shoe.
  • It runs true to size, as noted by some runners.

2 reasons not to buy

  • There is only one color option as of the current release.
  • A few claimed that the heel section does not hold their foot as well as the previous edition of this shoe.

Bottom line

The 8th instalment of the Fastwitch is a very light race day shoe that gets a little more cushioning for runs ranging from 5 to 10K’s. For very efficient and elite runners, this could be a superb option for half marathons as the lightweight stability keeps their form throughout the run. Besides having a more forgiving sole, the improved breathability and exceptional grip makes this an excellent option for those who are looking to lower their PRs.

    Lightweight, Stability & Speed All in One

    My first thought when I got these shoes is that they are not for running slow; they are for speed. It should be illegal to go slow with these shoes on.

    I came across Saucony have developed their shoes to be more durable than other sole material. As such, if you see signs of deterioration, it means you have run way too much on that shoe.

    I think they could last around 600 km, but I would not be surprised if you wanted to dispose them before that mark.

    What I like

    • Lightweight
    • Gentle stability

    What I dislike

    • Tricky to choose the right size


    If like me, you are looking for a (very) lightweight shoe that offers some degree of stability, you should definitely go for these.

    Also, unless you are an elite, you may find them suitable for track too; obviously not for a 100-meter race, but for distances of 800 m and further, they do their job well.

    They are ideal for 5 km and 10 km races but whether you choose to wear them for distances above half marathons is a personal decision.

Updates to Saucony Fastwitch 8

  • The changes in the 8th iteration of the Fastwitch are limited to the upper. For this version, the welded overlays are replaced with thin, fused versions that are as sturdy as stitched overlays, but without the weight. It is one of the reasons for the significant weight loss.
  • Another change in the upper is the new engineered mesh with larger and more numerous holes for enhanced ventilation. For those who run in humid climates, this shoe should ensure a sweat-free and dry run.
  • For aesthetic appeal, the plastic-like finishing of the earlier version is now more sophisticated. It offers the looks of a shoe that belies its very reasonable price tag.

Saucony Fastwitch 8 size and fit

Saucony brings back the fit of the earlier model in the Fastwitch 8. But, because of the softer mesh in this version, it accommodates various foot types a little better. The shoe offers excellent midfoot locked down while the rear section has decent security throughout every run. It runs true to size.


The Fastwitch 8 utilizes Saucony’s brand-exclusive PWRTRAC outsole with its numerous arrow-shaped lugs from the heel to the forefoot for superior traction, even in slick conditions. For flexibility and a smoother ride, a vertical cut from the heel to half the midfoot is carved in the underfoot. There are forefoot flex grooves that give the shoe excellent roll-offs.


The midsole is laid with the very light SSL EVA or injection molded EVA with Saucony’s own rubber properties. It covers the length of the midsole for a quick and efficient transition from landing to take off. The Fastwitch 8’s lightweight stability is mainly due to the medial post beneath the arch to curb mild over pronation.


An engineered mesh that is softer and more breathable covers a large part of the upper. The mesh works hand in hand with the FlexFilm overlays that are very thin, translucent, and fused for a really sophisticated look and lightweight support. An Ortholite Premium Sockliner provides anti-sweat, anti-microbial and anti-odor properties. It also enhances the cushioning of this shoe. A traditional lace-up closure keeps the fit secured until the run is finished.
