Customer Reviews

Comments: I used these for track. I would run the 400, 800, and 1600 in them. For me they work better than spikes. I also just won a 5k road race in them yesterday. Very comfortable, smooth transition. 
From: Chris, Lambertville, MI

p>Comments: These shoes are killer!!! As soon as I got them I ran a smooth 5k and medaled! Can't wait to use them again, because they are so light. Also, when I was running all I heard from the spectators was "nice shoes!!!" Seriously, they are great and recommend them to anyone who wants to do great in a race.
From: Peter, Goshen, NY, USA

Comments: These are probably a pair of the most versatile flats and the most bang for your buck. I'm not really a minimalist guy but I do a lot of my track work in these and they're perfect for giving you that light, fast feeling without wrecking your feet or calves in the process. I even use them at dual meets and scrimmages if I know the race isn't going to be too fast. I wouldn't replace my spikes for a pair of these, but they're definitely the next best thing on the track. Also, they have a similar feel to the Forever XCs (the new ones, my personal favorite for xc) but with a roomier toe box for long workouts and races. I would race up to 10k on the road without hesitation, but I know a lot of people use them for half marathons.
From: Rob, Long Island, NY, USA

Comments: Surprising amount of cushioning for a flat.  Only one run so far, but impressed and happy with purchase.
From: Anonymous

Comments: These things are great. I use them primarily on pavement, and run 50+ miles a week in them. They seem to only last 300 miles, but that's about when most people say shoes should be replaced anyways. I tried running in Vibrams and was never satisfied with them. Looking for a minimal shoe that I would be happy with I tried these out and love them. I'm on my second pair of them and plan on getting more.
From: Duane, Eugene, OR, USA

Comments: Best racing flat hands down! i used them for xc and they worked great! the see through mesh really trains water well. These shoes have alot of cushioning that you wont get with other racing flats. It is one of the lightest flats you will ever wear! I Ran my fastest 5k in this shoe. 
From: Anonymous

Comments: The XC 2 is the best racing and speed work shoe I have ever had. Doing interval workouts/reps, hill sessions and 5k to 10k races cross or road, the XC 2 is the shoe to go. I love its flexible, grippy Cushlon sole, spot on cushion and breathability/drainage. This is the first shoe I fully trust in every aspect.
From: Dominik, Fulda/Bayreuth, HE/BY, DE

Comments: The shoes are lightweight yet provide considerable cushion. They are true to size, cup the ankle nicely and are wide enough in the toe box to alleviate the stress of long run foot swell.
From: Eddie, Silver Spring, MD, CA

Comments: Runs long.. Order half size down!
From: Alva, San Francisco, CA, USA

Comments: I did quite well in my race this morning and I was very satisfied with the performance of this product. So, I have come to conclusion: this is most likely THE best XC flat I have ever purchased in my life. A conveniently lightweight and decently cushioned flat, I'd say the Nike Air Zoom Streak XC 2 is ideal for those seek a minimalist approach to distance (and don't mind running sans socks). You won't be let down.
From: Chris, Rancho Cucamonga, CA, USA

Comments: The shoes are really nice but they were a little too big. I have to get a half size smaller.
From: Tyrell, Lakewood, CA, USA

Comments:  Needed a replacement for the Katana Racer 3. Tried the Streak 3 first and found its high arch, more curved last and higher heel just didn't work for me, so I sent them back and got these.  So far these seem nearly perfect.  I have flat, flexible feet and land on my mid-foot, if that helps.
From: Matt, New York, NY, USA

Comments: GREAT FLAT!!! They are very lightweight, quite comfortable, and durable enough to last you at least 20 races. They tend to run 1 size to 1/2 size long. I normally wear a 11 and I wear 10 in these.
From: Joshua, Hartford, CT, USA

Comments: I love these shoes! My only beef is that the laces come untied very easily so you have to be careful to make the bow super secure before the race.  I use them for 5Ks and the occasional shorter speedwork day.
From: Tim, Orlando, FL, USA

Comments: Great racer, period. They have the same upper as the mamba's which are Nikes second lightest ever spike; so basically these things are ridiculous. Recommended for short distances, mile through the half marathon at max, not enough cushioning really even for the half marathon.
From:  Peter, Frederick, MD, USA

Comments:  Great shoe. Really light, wouldn't recommend them for anything over 10K because they are hard on your calves. Mine have started to lose tread in some places but only minor. Overall great flat
From: N., Wellington, NZ

Comments:  Great Shoes, I have ran 3 5k road races with them and they preformed well.  I love these shoes.
From: Eric, Whitefish, MT, USA

Comments:  I agree they run long. I wear a 9 in all other shoes but need an 8.5 in these, particularly when going without socks for races. Not great on technical trails but perfect for what they're made - combo XC courses with a little grass, dirt and pavement / concrete. The high heel collar is a little annoying - it's something I notice during a race.
From: Sky, Santa Rosa, CA, USA

Comments:  I love these!  They weigh less than air and are the most breathable shoes I've ever owned.  They are much better on pavement than trails - not much to protect your feet from rocks, etc.  But, they were made for road racing, not trail running.
From: Stuart, Huntingtown, MD, USA

Comments:  Indeed this is a lightweight shoes, very light!!!  And very low to the ground.  Not a lot of cushioning or support, but this isn't something made for the that crowd.  The arch area is quite narrow and it may feel strange at first try if you're new to this type of shoe.  I like these shoes but I won't be buying them again b/c they're made in China.
From: Ted, New York, NY, USA

Comments: Put over 600 miles on my pair before the midsole became part of the rubber.  Wore these shoes for road and trail up to 20 miles.  No doubt these will holdup for an efficient runner for a 50k. The mesh allows good drainage but allows trail debris to penetrate.  Very flexible for a flat.
From: Matthew, Seattle, WA, USA

Comments: SWEET!!! Right out of the box, ran a strong 10k road race. They run a bit long. I wear a size 10 in LunaRacers (snug). The streak is longer, but I wouldn't want to size down because I think they would be too narrow. With the right sock combo, size 10 is perfect. I thought I might wear them for a half-marathon, but 10k was pushing it for me. They're nice and firm and I'm sure they'll be awesome on the trails as long as the durability holds up. But what can you expect? They're almost completely transparent mesh.
