Saucony Fastwitch‏‎‏‎ Review

The Saucony Fastwitch‏‎ is a great shoe, similar in many ways to my long time favorite in this class, the Asics Gel Hyper Speed. While the Fastwitch it's often marketed as a 'racing shoe', I prefer to think of it as an optimal shoe, providing everything most runners need without the weight that comes with the over engineering of traditional running shoes. It's a 7oz shoe that I'd happily run the marathon distance in, and if I needed more cushioning than the Fastwitch I'd look to the Maximalist Hoka Clifton. The Fastwitch has the cushioning of shoes weighing (and costing) far more. It's only major problem is that the shape does not match the human foot, a failing shared by most running shoes. I've rated the Fastwitch as "Highly Recommended" and I've come to love running in it. (I use The Science of Running Shoes as the basis of how I test running shoes and what you should look for in a running shoe.)

1 Characteristics

• Cushioning . The Fastwitch‏‎‏‎ has outstanding cushioning for its weight, which is on par with the Asics Gel Hyper Speed. It's slightly heavier than the Hyper Speed, but it's a little bit more equal fore/rear. The cushioning feels smooth and even, feeling like you're running on a cushioned track, which is how it should be.
• Drop. The Fastwitch‏‎ has 4mm of drop when loaded, which is a tad more than I'd like, but it shouldn't cause any biomechanical problems. The main issue with that level of drop on a lightweight shoe is that it puts more of the cushioning in the rear and less in the forefoot, rather than balancing it out.
• Structure. The Fastwitch is a nice simple shoe that does not attempt to manipulate your stride. There's a single density of foam and only a slight rise under the midfoot that shouldn't create undue pressure on your arch.
• Flexibility. The Fastwitch‏‎‏‎ has great flexibility that allows the shoe to move naturally with your foot. This flexibility is rather greater than I might expect given the construction; it seems to come partly from the gaps in the outsole, but mostly from the midsole foam. Unlike many shoes that want to flex in just one place, the Fastwitch flexes more naturally.
• Outsole. The Fastwitch‏‎‏‎ has harder wearing rubber outsole under most of the contact area, providing reasonable abrasion resistance. Like most shoes with an outsole, the limit on longevity will be the midsole which will compress with mileage. There are some small gaps in the outsole, but I didn't find any problems with them catching stones.
• Shape. The Fastwitch‏‎‏‎ is not designed to fit a human foot, so I cut open the toe box to prevent my toes getting crushed and so my foot could move naturally. (I recommend cutting open the toe box of virtually all running shoes, with the exception of a few shoes like some Altra shoes. When you have some worn out shoes, you should try cutting open the toe box. I've found that it's a big improvement, allowing my toes to move naturally and engage for toe off, as well as reducing the possibility of blisters.)
• Upper. The upper is inflexible and mostly unpadded, but quite comfortable. The upper is largely seamless, having just a little padding around the rear of the foot and around the ankle opening.
• Tongue. The Fastwitch‏‎‏‎ has a traditional tongue that is has a tab to attach it to the laces. The tongue is rather more padded than the rest of the shoe.
• Lacing. The Fastwitch‏‎‏‎ has flat laces which have tiny bit of elasticity that seems to improve comfort and I've never had them come undone.
• Heel Counter. The Fastwitch‏‎‏‎ has rather more of a heel counter than I'd like. This adds weight and does not good, but it's also unlikely to cause any issues by rubbing or digging in.

2 How Far Can I Run in the Fastwitch?

Different runners want different levels of cushioning, so this shoe may not suit everyone. Some runners want a Maximalist shoe when they run a 5K, while others will run a 100 mile race barefoot. Most people find that as the distance increases, they want a little more cushioning to protect their feet from the pounding and to offset a little of the fatigue that sets in over time. You can see from the charts below how the cushioning compares with other shoes I've tested for some comparisons. Remember that a thicker, firmer shoe would have the same cushioning rating as a thinner, softer shoe, but would feel rather different.

3 Comparisons

Here are some direct comparisons with its potential competition.

3.1 Saucony Fastwitch‏‎‏‎ and Nike Zoom Streak LT3

The Nike Zoom Streak LT isn't as well cushioned as the Fastwitch, nor is its cushioning-to-weight-ratio as good. However the Streak is a far better shape than the Fastwitch and it's one of the few shoes I can wear without cutting open the toe box. It also lasts far longer than the Fastwitch and it's quite a bit lighter.

3.2 Saucony Fastwitch‏‎‏‎ and Asics Gel Hyper Speed

The Fastwitch and the Asics Gel Hyper Speed are really close, with the Hyper Speed providing slightly better cushioning for the weight.

3.3 Saucony Fastwitch‏‎‏‎ and New Balance RC5000v2

The Fastwitch‏‎‏‎ is quite light, but it's nearly twice the weight of the New Balance RC5000v2. The RC5000v2 provides just enough cushioning to improve Running Economy, so it will be a faster shoe than the Fastwitch. However, I suspect most folks will appreciate the extra cushioning of the Fastwitch.

4 A Comparison with other Recommended Shoes

If you're looking for "the best of the best" running shoe, here are my top picks. Of course, the answer will depend a little on what you're looking for, so I have recommendations for various categories. Best All Round Shoe. The Altra Escalante is my current all-round favorite. It has plenty of cushioning for its weight, it has a very springy midsole, it lasts well, and it has a shape that's closer to the shape of a human foot than most shoes. It's a great shoe for any runner, including those Starting to run. It's also a fairly easy shoe to find due to its popularity. Best Maximalist Shoe: If you want something massively cushioned, then I'd recommend the Saucony Kinvara 8. It's remarkably light and remarkably cushioned, beating Hoka at their own game. Best Optimal Shoe: For those looking to trade cushioning for speed, the Nike Zoom Streak LT 3 was my top pick, but the latest version (LT 4) falls short of it's predecessor. There are lots of great optimal running shoes, which provide just enough cushioning with light weight and minimal frills, but all have their weak spots. Probably the best option at the moment is the Altra Vanish-R, which offers great cushioning for just over 5oz/150g. Fastest Shoe: If you really want speed, then check out the Nike Vaporfly 4%. It's light, massively cushioned, and has a carbon fiber plate. Nothing comes close, not even the now defunct New Balance RC5000‏‎ or New Balance RC5000v2‏‎. There are a number of caveats; it's really expensive, it's really hard to find, and there's a significant injury risk. Best Minimalist Shoe: Merrell Trail Glove. I recommend the trail glove for road running in spite of the 'trail' moniker. It's not a fast shoe by any means, but it's comfortable and will last well. All Terrain Shoe. For trail running, I've become a fan of Altra, and I think their best shoe is the the Altra Timp, though the Altra Lone Peak is really close. Honorable Mention: It's not really a running shoe, but the Vivobarefoot Ra is comfortable, minimalist and can more or less pass as a dress shoe. I've worn mine to weddings with a suit and they've not looked out of place. You can run in the Ra, but the leather means it doesn't breathe well.
