Summary:
This racing flat from Saucony provides a unique blend of flexibility and support. It features a small medial post to give stability to runners with moderate overpronation. A snug fit and flexible forefoot make this shoe feel extremely fast however there is a surprising amount of protection in this shoe so it doesn’t feel flimsy.

Changes:
Saucony tinkered with the materials in the upper to shave 0.3 oz off the weight without sacrificing any of the cushioning properties. The new upper has a slightly roomier fit but this shouldn’t be a problem for those who have enjoyed previous versions of the Fastwitch.
