A+ lightweight stability racing flats


I use these shoes for my mid-week runs only and not for my long runs because these are not shoes that you should be running high mileage in. They are primarily racing flats. I have been wearing Brooks Adrenaline for almost 10 years which are 9.4 oz and a very supportive shoe. I was looking for a more lightweight shoe to race and do speedwork in that would still have some stability and not make a mess of my legs in the transition because going from the Adrenalines to a racing flat is a huge jump. I found these because they were in the Performance Stability category and they were exactly what I was looking for, and advertised as 6.2 oz! The structure of the shoe actually feels very similar to the Adrenalines so I think it is a good pairing if you're looking for a more lightweight shoe. I found that there are two major differences between more supportive shoes and the Fastwiches. The first is that the heel drop in the Fastwiches is 4mm while it is 8mm in the Adrenaline and many other stability shoes (so you will feel your calves working a bit harder). And second, the Fastwitches have significantly less cushioning than more supportive shoes which is why they are not meant for high mileage. Over all I am extremely happy with these shoes. I had tried other lightweight shoes, specifically the Brooks Pure line, but they were way too narrow. The Fastwitches have quite a wide mid-foot to toe-box area which was a key trait I was looking for. However, the shoe does run a little small: I usually wear a size 8 and I had to get a size 8.5.

So far so good!


Run about 40 miles a week and have been dealing with piriformis syndrome, hamstring injurues. I have gone through several running shoes in the past few months trying to find one that was lighter but had more stability, (I found something wrong with every shoe- too high, not enough support, gave me blisters) I read every review and looked at the weight of all styles, I also used the iChat feature to ask more questions and make sure I was asking the right questions based on all the styles I sent back. Happy to say I like this one, it's lightweight and not too high, So far I am happy with it and would order again. The color is bright and shows up in the dark. Had had compliments on them! They did feel tight in the toe in my normal size so I ordered a half size up snd they fit much better.

Two days after receiving these shoes, I did a 5K. Not my usual 5K, it was so crowded, I did quite a bit of walking. But these shoes were comfortable. Not stiff...felt like they were already broken in. I have been wearing Saucony's for years now so I knew that I have to order a size and 1/2 up. I wear a 9 in regular shoes but wear a 10 1/2 in Saucony running shoes. The fit is perfect. These shoes are also VERY light. When I picked up the package at my front door, it almost felt empty. If you want thick soled, heavy shoes, these are NOT for you. For our hot humid summers, I'm going to love them!

Too much stability


Probably not the shoe. It felt light and the arch support was good. I have spent the last year in a minimalist shoe when I'm able to run. Was working on increasing milage and felt as though I needed additional support. Tried these as they are minimalist but do offer some stability, and my feet screamed. Couldn't wait to take them off. Too much stability. Full disclosure, after numerous injuries and arthritis under my toes, I was not able to run much at all last year, so it could be the pain I noticed with my minimal shoes could have been too many miles too soon. At this point, I'm sticking with neutral shoes like the Saucony Mirage II.

Running less than I'd like

LOVE these!!!


I was looking for a pair of shoes with a low heel drop that also helps control over pronation and these shoes are perfect for that! These help me with my midfoot strike and are super light so it doesn't feel like you're running with bricks on your feet. The fun, bright colors are a plus. The only reason I'm giving this 4 stars and not 5 is because it runs SUPER small. I normally wear an 8.5 in running shoes but had to get a 9.5 in these... and my big toes still feel a little too close to the top.

Love these Fastwitches!

Feel the road


I've been out about 100 miles with these shoes now. They are light weight, definitely feel the road beneath you, but has just enough cushion for a comfortable ride. My only con is that all my socks get very dirty with these shoes. Notice in the photos there are holes in the sole. So there are areas in the bottom of the shoe that expose the foot compartment. Only thing separating my foot from outside is thin cloth. Since I run on dirt and gravel, my socks are filthy.

very light


was waiting for a day when it wasn't wet and muddy but gave up on that considering it is February in NY. Went out for a run and my feet got wet immediately, thought it was beacause sole was very skinny and driveway was wet from rain and melting snow, but relized that there 4 holes in sole of shoe that go all the way through. Not a problem just won't wear unless it is dry or just running on dry pavement or track.






I have a weird issue were my feet fall asleep when I run for no reason and for whatever reason these really helped. I don't run with them anymore but I go to the gym. However when I got them I was finishing off a distance track season so I can defiantly say these are amazing shoes for people who run a lot and want stability but still something a bit lighter.

Even lighter than the 5


I replaced my fastwitch 5 with these and was impressed becasue they are even lighter yet have great traction. I was not a great fan of the color, but it's OK. I order a full size more than what I wear for regular shoes because the toe box is a bit narrow. They are very durable, and I'm still racing in the fatwitch 5 even if they are over 400miles. I'm expecting the 6 to be on the same path.

Great, but size up


I bought these for race day, primarily half marathon distance. I am very pleased! I don't like a shoe with a large heel drop so the 4mm is within a range I run in. They offer the right amount of stability for a mild overpronator. I like the roomy toe box and overall fit. I wear a 7.5 in most running shoes and best on recommendations, ordered an 8 in these and it worked well.




Great race day shoe...


I use these strictly for race day. I used them in my last race and I swear my pace was faster. I'm new to running, but I would recommend these shoes only for race day. I use a stability shoe for my training and put the Fastwitch 6's on those days I'm practicing a race :) Great shoe if you need some stability, but want the feel like you have no shoes on your feet.

Fast yet stable shoe!


Fast, stable and light shoe. Great for speed work and distances through 10k. I think its too firm to go up to the marathon distance; possible half-marathon racer if your an efficient runner. Fun shoe to use for speed work; love the slime green color! I did size up 1/2 size from my normal running shoe and it was perfect.


Grand Blanc, MI


Great shoe, but runs VERY small


I purchased these to use as racewalking shoes, and so far they're working out very well -- very lightweight but stable. The only thing is that they run VERY small. I'm a size 9 in street shoes and had to order a 10.5!


Setauket, NY


Good Shoe!!


Good shoe!! I think these are great for indoor gym! minimal cushionining in the toe area. Suites the purpose and more ; )




Perfect for insanity!


These have made my insanity workout so much easier!
