The Fastwitch has been a racing staple in the Saucony line for nearly a decade. Round 6 continues to focus on racing while zeroing in on some specific features. The midsole retains the high-quality EVA and dual-density design, along with its low-profile geometry from Round 5.
Its profile and cushioning are aided by the co-molded ESS shank for a touch more support and stability. The outersole setup is unchanged, though minor tweaks—cosmetic, though perhaps also with a technical purpose—are apparent in its current form. The upper has received the lion’s share of the attention, as is often the case in racer updates. The closed mesh has been replaced with an open mesh of small ovals, combined with a saddle of FlexFilm and stiffer, closed mesh that holds the foot securely. The good news is that the Fastwitch 6 is a stable, protective racer with a broad size range. And, even better, it’s still suitable for faster races.
