INTRODUCTION

The Grid Fastwitch 5 is a moderate feature, minimum support shoe designed for speedwork and racing. It is built with a semi-curved shape.

CUSHIONING

  • To keep weight down, this shoe contains no additional cushioning technologies.

MIDSOLE

  • Dual Density SSL EVA uses high density EVA in the midfoot to control overpronation, and a SSL (Saucony Super Lite) midsole material throughout the remainder of the shoe for lightweight comfort, rebound and durability.
  • Midfoot Support Bridge is a thermoplastic unit that extends from the heel through the midfoot for increased torsional rigidity.
UPPER
  • Open Mesh covers the entire upper and is a breathable lightweight fabric.
OUTSOLE
  • XT-900 is a carbon rubber material that offers durable traction.
  • EVA+  is utilized in the forefoot for increased traction.


Comments: I've run in the Fastwitch since they first came out. Always sad to see a good shoe ruined.

Comments: I have a pair of Fastwitch 4's that I have run into the ground and I really liked them.  I find the 5's to run smaller than the 4's (ordered my same size and it didn't come close to fitting) and also to be really inflexible compared to the 4's.  Hated the 5's and returned them.

Comments: Fastwitch 3&4 were great.  The 5 is terrible.  I hope they bring back the 4.

Comments: I just used these for the SF Marathon, my second full marathon. I have slight classic everyday pronation as a runner of 5 ft. 9 and 151 lbs. They did the job - secure feel, light, not to snug, didn't feel inflexible. I have not used the previous version to compare them, so I can't speak to the 4 vs. 5 comments. I can say that last year I used the Asics DS Trainer 15 for the same marathon and was not impressed with the forefoot on that shoe vs. this one. The DS made me feel all the cracks and little stones in the road much more so as the mileage went up, but the Fastwitch did a better job for me.

My thought would be that if you are running a course with lots of hills like SF, get a better support shoe. On the hills, I would have liked more support in the shoe for my pronation, especially as I fatigued in the last 6 or so miles. I'm already looking at the Zoot Ultra Ovwa for my next race shoe. I have tried them on and feel like they will be the perfect race shoe for me, given my form. I can say that I did set a new PR by over 7 1/2 minutes, so the Fastwitch 5 certainly didn't hurt me. I normally trained in the Progrid Mirage for a more bare, but not too bare, running experience and still enjoy them. But race day and 26.2 requires more support for me.

Comments: Been running in these shoes for 200 miles now and love them. I came from the Elixir 5 and I love the heal drop of the Fastwitch 5 compared to the Mizuno. The little bit of support is just perfect for long runs when my form gets sloppy. The rubber is nice and sticky but wears some what quickly. These are a great racing flat and half marathon shoe.

Comments: loved the fastwitch 4 and HATE the 5...not even close to flexibility of the "old" one...now have to buy the 4 on ebay or somewhere else. hope saucony will realize the mistake they made and fix that with the 6!
From: E, Charlotte, NC, USA

Comments: I agree with a previous post.  Saucony ruined a great racing shoe.  The Fastwitch 4 was great, but the Fastwitch 5 has an awful feeling with the low heel/toe ratio.  Saucony should have continued the high heel/toe drop with the Fastwitch - and then came out with a different name for the low heel/toe drop racer.

Comments: These shoes are terrible. Let me back up... I was a HUGE fan of the Saucony Grid Fastwitch 4 shoes. They were light, responsive, and very flexible. But these? I feel like there is a cardboard box taped at the bottom of my shoes. The shoe isn't flexible at all so when you push off the ground, instead of the fabric just flexing naturally, it bends and puts lots of pressure on your toes. I think it's a good thing that Saucony decided to cut some of this shoe's heel to promote more forefoot running, but they did it at an expense of flexibility. I am not a beginner runner. In fact, I average 50-70 miles a week but when I wore these shoes and running after 3 miles, I had to walk those 3 miles back because of feet pain. I never really complained about running shoes until now. I do not recommend this shoe.
From: Arkady, Los Angeles, CA, USA

Comments: I am a relatively lightweight runner (120 lbs) who has shifted to a more forefoot style of running over the last year. Previously, I wore the Asics Gel 1140, but I was looking for something that was lighter and with a less built-up heel. Also, I have narrow feet and I prefer a shoe with a more responsive, firm feel. The Fastwitch 5 delivers in all of these categories. The shoe feels light, almost like a racing flat, but it still has enough support for my flat feet in the medial arches. Also, the low heel promotes a more forefoot type of stride. However, the thing that sold me on the Fastwitch 5 was the fit. The foam in the back of the shoe perfectly holds my heel in place and the rest of the shoe snugly grabs the top of my foot while still giving my toes some room for movement. So far, I have worn these shoes on two four-mile runs (one fast and one slow) and a hill work out, and they have felt light, fast and comfortable for each. My only suggestion for this shoe is more color options (maybe black or blue?.) I have the white colorway and I'm hesitant to run through puddles or anything else that would stain the beautiful exterior.
From: Daniel, Tempe, AZ, USA

Comments: Did a 4 mile break in run then followed that with a 12 mile run, 10 of which were a tempo run. Love these shoes. I like the touch of support they have from the medial post. I bought them as my Boston Marathon shoe, but don't think I am efficient enough to use them for that distance. They feel very flat and light which promots a more barefoot like stride and they are also very comfortable. Couldn't be happier with my purchase. The green color rocks too!
