The Saucony Grid Fastwitch is an incredibly versatile shoe with a generous fit in the forefoot (though you may need to size up to feel it). As a structured flat, it can be used for speedwork, long runs, and just about anything else. I’d feel very comfortable wearing it for a marathon, though personally I’d opt for something a tad lighter and stiffer in a 5K.
This is a great shoe if you like a really firm ride or like stiff support in a racing shoe-like package with decent room in the toe-box.
I definitely think there are significant improvements that can be made in the sole to lighten the shoe up and turn it into the racing monster it deserves to be.
It is low profile, stylish, and superbly comfortable even though there isn’t as much material as in some running shoes. The low profile also makes this an extremely light shoe, which is ideal for competitions and marathon races.
Updates to Saucony Fastwitch 6
- The upper is updated with the FlexFilm technology and it comes with a dual-density open mesh material for breathability. It stretches well on the feet allowing the toes to move with less of the restriction.
- Saucony also enhances its upper design with welded overlays. Part of its update is its reduced weight due to the overlay. The inner upper has a super soft ankle collar that adds comfort to the foot. An ortholite insole is also added, and this can be used or removed depending on the runner’s preference.
- Being a stability racing flat, this shoe also features a plastic heel counter, making the sole firm, responsive, and stiff, which is quite typical in any racing flat shoes.
Saucony Fastwitch 6 size and fit
The Fastwitch 6 runs small compared to the standard fit and sizing. Although it has a wide toe box, it is fit for small to medium mid-foot, heel, and toe areas.
The outsole of the Fastwitch 6 is equipped with the Saucony exclusive XT-900 extensive carbon rubber material. This technology offers exceptional traction and grip and durability even on wet grounds.
The midsole comes with Dual Density SSL EVA foam for its lightweight cushioning. The midsole is also designed with medial post that provides stability and firmness. From the heel to the mid-foot area, Saucony also placed a Mid-foot support bridge to help in the pronation control, thus making the shoe stiff and rigid for a more responsive and efficient racing flat for over pronators.
The FlexFilm in the upper of the Fastwitch 6 is the overlay added to the Lightweight breathable mesh materials. This is not sewed, which makes the shoe a lot lighter. It is also responsible for the comfort fit the shoe has, keeping the foot snug and comfortable. Premium Sockliner is also added in the inner area for maximum comfort and softness.
