What Are A6 Shoes? Understanding the Saucony Type A6 Legacy
When runners mention a6 shoes, they're typically referring to the legendary Saucony Type A6 racing flats that revolutionized competitive running footwear in the early 2010s. As someone who witnessed their debut at the 2013 Summer Outdoor Retailer show, I can attest to the immediate excitement these shoes generated among serious runners and industry professionals alike.
The Saucony Type A6 emerged as the sixth iteration in Saucony's acclaimed Type A series, building upon years of innovation in lightweight racing shoe technology. What set these a6 shoes apart was their remarkable combination of minimal weight—just 5.2 ounces for a men's size 9—and surprising durability for such a stripped-down racing flat.
During my first training session with the Type A6 in fall 2014, I immediately noticed how they seemed to disappear on my feet. The sock-like FlexFilm upper created such a seamless feel that I often forgot I was wearing racing flats during tempo runs. This characteristic became the hallmark of a6 shoes and explains why they maintained such a dedicated following throughout their production run.
The A6 represented a significant evolution from its predecessor, the Type A5, which many runners criticized for durability issues. Saucony's engineering team completely redesigned the outsole, replacing the problematic rubber nubs with strategically placed carbon rubber sections that provided superior grip and longevity. This improvement made the a6 shoes suitable for both racing and high-intensity training sessions.
Understanding the legacy of these shoes requires recognizing their intended purpose: to provide competitive runners with the lightest possible racing flat while maintaining enough protection and response for distances up to the marathon. For runners exploring different footwear options, our comprehensive shoe guide offers valuable comparisons with other racing flat options.
Key Features and Technology of A6 Shoes
The technological innovations in a6 shoes represented Saucony's commitment to creating the perfect balance between weight reduction and performance enhancement. Having dissected multiple pairs during my testing process, I can provide detailed insights into each component that made these racing flats exceptional.
FlexFilm Upper Construction
The FlexFilm upper technology in a6 shoes marked a revolutionary approach to racing flat construction. This lightweight synthetic material replaced traditional overlays and stitching, creating a seamless, sock-like fit that eliminated potential friction points. During my extensive testing, including a challenging 15-mile tempo run through Rocky Mountain National Park, the FlexFilm upper never caused blisters or hot spots, even when running sockless—a testament to its smooth interior construction.
SSL EVA Midsole Technology
Saucony's SSL (Super Lite) EVA midsole represented their most advanced cushioning system at the time. This proprietary foam blend provided exceptional energy return while maintaining the firm, responsive feel that competitive runners demand. The 4-5mm heel-to-toe drop in a6 shoes promoted efficient running mechanics, particularly beneficial during my track workouts where ground contact time is crucial for speed development.
XT-900 Carbon Rubber Outsole
The XT-900 carbon rubber outsole system solved the durability issues that plagued earlier Type A models. Strategic placement of high-wear rubber in key areas extended the lifespan of a6 shoes significantly compared to their predecessors. The three drainage holes, while occasionally collecting small debris, enhanced wet-weather performance during my rainy season training in the Pacific Northwest.

Performance Review: My Experience with A6 Shoes
My journey with a6 shoes began in October 2014 when I first laced up a pair for a 10K time trial. The immediate sensation was remarkable—these shoes felt like natural extensions of my feet rather than bulky footwear. This initial impression proved prophetic during the subsequent 18 months when I accumulated over 500 miles across various training conditions and race distances.
Race Day Performance
The true test of any racing flat comes during competition, and a6 shoes consistently delivered exceptional performance. My personal best 5K time of 18:32 came while wearing the A6 during a crisp November morning race in Boulder, Colorado. The shoes' responsive midsole provided immediate energy return with each stride, while the lightweight construction eliminated any sensation of foot fatigue even during the final sprint to the finish line.
Training Versatility
Unlike many racing flats that serve solely as race-day weapons, a6 shoes proved remarkably versatile for training applications. During my marathon training cycles, I regularly used them for tempo runs, track intervals, and even some longer aerobic sessions. The key was respecting their limitations—anything beyond 15 miles began to reveal the minimal cushioning, but for most quality training sessions, they remained comfortable throughout.
Durability Insights
One of my initial concerns about a6 shoes centered on longevity, given their stripped-down construction. However, they consistently exceeded expectations. My first pair lasted approximately 400 miles before showing significant outsole wear, primarily in the forefoot contact areas. The FlexFilm upper maintained its integrity throughout this period, with only minor scuffing from trail debris during occasional off-road excursions.

A6 Shoes vs Competition: How They Stack Up
During my extensive testing period, I ran comparative sessions wearing a6 shoes alongside leading competitors including the Asics Gel Hyper Speed 6, Nike Zoom Streak LT 3, and New Balance RC5000. These side-by-side comparisons revealed distinct characteristics that set the Saucony Type A6 apart in the competitive racing flat landscape.
Weight and Construction Comparison
At 5.2 ounces, a6 shoes occupied the middle ground between the featherweight New Balance RC5000 (3.1 ounces) and the more substantial Asics Gel Hyper Speed 6 (6.4 ounces). This positioning proved strategically important—the A6 provided more protection than ultra-minimal racers while maintaining the speed advantage over heavier alternatives. The FlexFilm upper offered superior comfort compared to the sometimes harsh feel of lighter competitors.
Cushioning and Responsiveness Analysis
The SSL EVA midsole in a6 shoes delivered a unique combination of firm responsiveness and subtle cushioning that distinguished it from competitors. While the Asics Gel Hyper Speed provided more traditional gel-based cushioning, the A6's foam felt more connected to the ground. During tempo runs, this translated to better pace control and more precise foot placement, particularly valuable during technical trail sections.
Durability Advantages
Perhaps the most significant advantage of a6 shoes was their durability compared to other racing flats in their weight class. The XT-900 carbon rubber outsole consistently outlasted competitors, particularly the Nike Zoom Streak LT 3, which showed premature wear in the forefoot region. This longevity made the A6 more cost-effective for regular training use while maintaining race-day performance capabilities.

"I've been using a6 shoes for three marathon training cycles, and they've consistently delivered exceptional performance. The lightweight feel never gets old, and I've achieved personal bests at both the 10K and half marathon distances. The only minor complaint is the narrow fit, which took some getting used to, but once broken in, they're incredibly comfortable for racing. Highly recommend for serious runners seeking that extra edge."

What to Look for When Buying
When purchasing a6 shoes, especially from secondary markets, inspect the outsole wear patterns carefully. Excessive wear in the forefoot or heel indicates heavy use that may compromise performance. The FlexFilm upper should show minimal stretching or discoloration, and the drainage holes shouldn't be damaged or enlarged beyond their original size.
Sizing and Fit Considerations
Unlike some earlier Type A models that ran small, a6 shoes fit true to size but run narrow. Runners with wide feet should consider sizing up by half a size or exploring width-specific alternatives. The snug heel construction can make initial entry challenging, but the heel pull tab significantly eases this process once you develop the technique.

The A6 model weighs only 5.2 ounces for a men's size 9, making it one of the lightest racing shoes available. The shoe features FlexFilm upper construction, SSL EVA midsole technology, and an XT-900 carbon rubber outsole. While discontinued, they remain highly sought after by competitive runners who appreciate their unique combination of lightweight design and durability.
How much do A6 shoes weigh and what's the drop?
The Saucony Type A6 shoes weigh approximately 5.2 ounces for a men's size 9, with women's versions being slightly lighter. They feature a low 4-5mm heel-to-toe drop, which is typical for racing flats and promotes a more natural running stride. This minimal drop helps reduce weight while maintaining adequate cushioning for racing distances.

Many elite runners have successfully used them for marathon distances, though most recreational runners find them more suitable for shorter races due to their minimal cushioning. The lightweight construction and responsive feel make them excellent for tempo runs, track workouts, and race day performance. For training applications, they work best for high-intensity sessions like interval training, fartlek runs, and tempo efforts. The firm midsole and low drop promote efficient running mechanics particularly beneficial for speed development and race situations where every ounce matters.
Are A6 shoes still available or discontinued?
The original Saucony Type A6 shoes have been discontinued and replaced by newer models in the Type A series, including the Type A8 and Type A9. However, you can still find A6 shoes through specialty running retailers, outlet stores, and online marketplaces like Amazon and eBay. Some running stores maintain old inventory, and the secondary market remains active among enthusiasts who prefer the A6's specific characteristics. When purchasing discontinued models, verify authenticity through reputable sellers and inspect the shoes carefully for wear. Saucony's current racing flat offerings continue the Type A legacy with updated technology and materials.
How do A6 shoes compare to modern racing flats?
While A6 shoes lack the carbon plate technology found in modern super shoes, they remain competitive for their intended purpose. They offer excellent ground feel, durability, and a pure racing experience without technological assistance. Modern racing flats often provide more cushioning and energy return through advanced foam compounds and plate systems, but the A6's simplicity and lightweight design still appeal to runners seeking traditional racing flat characteristics. The FlexFilm upper was ahead of its time and compares favorably to current seamless construction techniques. For runners who prefer minimal, responsive footwear over heavily engineered solutions, the A6 remains an excellent choice.
What should I look for when buying A6 shoes?
When purchasing A6 shoes, check the outsole for excessive wear, ensure the upper material (FlexFilm) isn't damaged, and verify proper sizing as they run true to size but narrow. Look for drainage holes that aren't clogged with debris, and inspect the midsole for compression or visible damage. Since they're discontinued, buying from reputable sources is crucial to avoid counterfeit products and ensure you're getting authentic Saucony quality. Consider the shoe's intended use—if for racing only, minor cosmetic issues may be acceptable, but training applications require structurally sound footwear. Always try them on if possible, as the narrow fit may require sizing adjustments for some runners.
