Customer Reviews

Comments: The size is way small, at least one full size smaller.
From: Marcia, Boston, MA, USA

Comments: Very narrow. I had a problem putting my foot in when I got them. I'm not even going to bother trying to break them in. Sending back for a refund.

Comments: LOVE THIS SHOE! Ordered on a whim while looking for another pair. I think my feet actually made an, "AHHHH!" sound as I tested them. It's a great transition to minimalist shoes with the 4mm drop. I usually tend toward a zero heel drop, but incorporate various styles so that I'm not pounding the same muscles and tendons constantly during runs and these do just the trick. Since Saucony tends to change their versions way too much (grrr!), I ordered another pair as back up since the next Fastwitch might fit so differently! The toebox is nice and wide, but not so loose as to cause blisters. The shoestrings, like all Sauconys, are too long, but that's easily remedied. Usually don't care about shoe color (except white, I HATE white shoes!) but ended up ADORING the red color. My husband said they looked like the ruby red slippers -and suggested maybe that's why they were called Fastwitch! :) Anyway, they are superlight which I've found to make a HUGE difference, they have just enough padding to be luxurious on road runs. Not sure how they will wear long term - fingers crossed. Someone mentioned not liking the words on the heels, but I LOVE the words! So sassy, and it's definite motivation as I pass other runners! Only buy these shoes if you are cool enough. ;)

Comments: I bought these for a half marathon back in January. Every time I race in them be it 5K -half marathon I'm left with blisters. Thy are not too comfortable and the laces can be a bit too long and bothersome.
From: Christy, Miami, Florida

Comments: Very comfortable, light ride.  Narrower in the toebox than previous Fastwitch versions. Great cushioning (I'm a mid-foot strike), and great road traction. And, of course, the purple and lime green is fabulous!

Comments: I also ran in the fastwitch 1 and 2. I became less enamored with each successive version. I am tired of saucony, and all shoe companies in general, changing size, fit and overall function from version to version. I am tired of the "barefoot" trend too. Note to shoe companies and people who have moved to it - there were always low profile, light shoes for people who raced, trained quickly or were slight framed; they were called performance trainers. The general public wanted more cushioning and more stability in the early 2000s and ruined every shoe out there. Now the general public wants "barefoot". Thanks for making running a trend like bell bottoms or grunge. I agree, Vicky, if you lower the heel but build in the front, doesn't actually make the shoe lower profile, just unnatural. I also won't be buying saucony again. I have worn every version of the tangent (until they discontinued it, the azzurra, the swerve and also wore about 20 pairs of the hurricane (first and second version) which was a minimal stability shoe until they changed that into a big beast of a shoe. There currently isn't a pair in their line up that even resembles a shoe that I could wear. Not to mention how every shoe on the market is so wide that I just slip around. Maybe running isn't for runners anymore?

Comments: I started racing Fastwitch with the first version. I loved the fact you didn't have to break them in and they had the right mix of lightweight material, cushion and support. The shoe was light yet you didn't feel every bump or rock in the road. But the Fastwitch 5 changed all of that. It is not a slightly tweaked version of the 4. It fits like an all new shoe. The toebox is wider and shorter. It's much stiffer and the padding under the ball of the foot is stiffer. It also feels like there's more padding under the ball. This makes you feel like your heel is lower. Maybe they're trying to copy Newton with the built-up ball. I don't like Newtons, and I sure didn't like the feel of the new Fastwitch 5. I tried on the 5s right out of the box and they started hurting my feet. Despite adjusting the laces, they still were uncomfortable as I walked around my house. I put on my old 4s, and they felt wonderful. The 4s' toebox is a bit longer so I have that recommended 1/2 inch between my big toe and the end of the shoe. With the 5, my toe is pretty close to the end. If you've liked the earlier versions of the Fastwitch, you'll be disappointed with the Fastwitch 5. Saucony broke the old rule: if it ain't broke, don't fix it. The Fastwitch wasn't broken, but they sure as heck fixed it and in doing so they wrecked what was an old mainstay. I returned the 5s and won't be buying Fastwitch again.
