Saucony actually has two Fastwich racers: the Speed and the Endurance. Both are excellent choices for racewalkers. The Endurance offers a bit more support, the Speed a faster feel. The Endurance is a great pick for heavier walkers who still want to knock out the miles, or for those suffering from plantar-fasciitis. The added “stiffness” under the arch makes for a somewhat slower transition to the forefoot, but that’s a fair trade-off if it prevents sore feet in the later miles of marathon or long training walk.
