All Women's Road Shoes

  • Daily TrainersDaily Trainers

    As the broad base of the running shoe pyramid, daily trainers are the definition of a go-to running shoe. They prioritize dependable comfort, support, durability, and routine versatility. They're a staple in every runner's closet. If you're newer to running shoes, you can confidently start your journey here.

  • Performance TrainersPerformance Trainers

    Performance trainers (or "super trainers") blend elements of daily trainers and super shoes, often giving you the benefits of advanced foams and plates, but adapted for daily training. They make fast runs faster and long runs easier. Highly versatile, many are also great choices as accessible racing shoes.

  • Race Super ShoesRace Super Shoes

    The pinnacle of the pyramid, super shoes are the fastest running shoes you can buy. They're designed to race your absolute best and are the apex of running shoe technology and innovation. Often built with carbon-fiber plates and cutting-edge superfoams for the highest energy return, they're made for ultimate racing speed.

Women's Running Shoes by Surface

  • Roads & PavementRoads & Pavement

    Road running shoes feature smooth outsoles that are designed for running on paved surfaces such as roads, sidewalks, and bike paths.

  • Smooth Trails & FireroadsSmooth Trails & Fireroads

    Designed to handle most trail runs, these shoes prioritize comfort and a smooth ride. These shoes are great for anything from smooth singletrack, park trails, and fireroads making them ideal for those who run from their doorstep on streets before hitting the trail.

  • Rocky & Technical TrailsRocky & Technical Trails

    These shoes are best used for hard, rugged trails such as shale, granite or sandstone where grip on smooth surfaces and underfoot protection are important.

  • Soft & Muddy TrailsSoft & Muddy Trails

    Designed for use in muddy, soggy conditions, these shoes feature very aggressive outsoles that dig deep into soft ground for exceptional traction.

  • Snowy & Icy TrailsSnowy & Icy Trails

    These shoes feature technical outsoles designed to grip snowy and icy trails making them ideal for winter trail running.

Stability Level

  • Neutral Running Shoes

    Neutral shoes support the foot through a normal range of arch collapse and generally do not have built-in technology to correct movement.

  • Stability Running Shoes

    Stability shoes are a great option for those who overpronate or need added support. These shoes help to limit the inward rolling motion of the ankle while running or walking and assist in guiding the foot straight through the gait cycle.

Stack Height

  • Stack height refers to how much shoe is between your foot and the ground. For this category, we reference the amount of material below the forefoot, as the heel height will be equal to or greater than the forefoot height.

    Learn more about stack heights and how we measure them.

  • Minimal

    14-18mm. The shoe has a thin midsole that allows for a natural running experience. Racing shoes and minimalist shoes are common here. These shoes offer a feeling of being connected to the road or trail.

  • Low

    19-23mm. The shoe has a slightly cushioned feel and may feature added cushioning technologies. Performance training shoes and some trail shoes are common here. These offer protection during footstrike but prioritize a lightweight, grounded experience.

  • Medium

    24-28mm. These shoes have a stack height that falls near the middle of the spectrum. The shoes in this category are versatile and great for all types of runs and distances.

  • High

    29-34mm. The shoe has a thick midsole and ample cushioning. These shoes are highly protective and absorb more impact than the body.

  • Maximal

    35mm plus. The shoe has an extremely thick midsole and extra cushioning. The focus is on protection and soft foam underfoot with hardly any ground feel.

How We Measure Our Shoe Specs

  • We measure every shoe in-house to provide accurate and consistent details.

  • Weight

    Weight is measured per single shoe, including laces. Men's and unisex styles are based on a men's size 9, and women's styles are based on a women's size 8.

  • Heel Stack

    The heel stack refers to how high your heel sits above the ground when wearing shoes. Based on Men's size 9 as the standard.

  • Forefoot Stack

    Forefoot stack refers to how high the ball of the foot sits above the ground when wearing shoes. Based on Men's size 9 as the standard.

  • Heel-toe Offset

    Heel-toe offset (drop) is the difference in height between the heel stack and the forefoot stack. We use the number given to us by the brand.

How We Measure Shoe Fit

  • All measurements are based on Medium width. Note: fit is relative to the "average" running shoe.

  • We partner with SmartLast, a program by Heeluxe, to use advanced shoe-measuring technology, to provide objective measurements for toe box, midfoot, and heel widths as well as overall length.

  • Engineered mesh creates airy enduring comfort and security with 75% recycled polyester.

6 to 7 month update......Since my last review of this shoe, I've grown to really enjoy this shoe...... took a bit of transition time, but this is probably one of the funnest/ lightest/ most fast shoes out there. I use this shoe primarily on trails and it is a very wild sketch ride !!!!!! My previous fav "trail" shoe was the Super Blast 2. I like the Megablast on trails because of the weight, foam, and minimal (but effective) upper. The shoe feels like it has a built in motor.....when your bodyweight compresses the midsole, quite a lot of spring back results. The Flight Foam in the SB2 most definitely constrains that shoe's performance. With the full midsole of Turbo sqared, there is no frmness/harshness. I have a wide toe splay and Im not having any issues with the upper width/height. The upper keeps my foot on top of the midsole even through extended off chamber. I use this shoe for fireroads, singletrack climbs, descents...... the outsole is definitely not appropriate, but the shoe is too fun. Outsole edges have delaminated a bit . I probably have over 400 -500 hard running miles and the foam feels factory fresh.....?. Me - 155lbs, trails only, 30 -50mpw, 55 laps around the sun, and I use the Megablasts on dry/damp trails.

feels a bit betaIm using this shoe as an easy day recovery shoe, slower than 9 minute pace, dirt carpet, roller terrain. My main shoe is Superblast 2. For myself, this upper material is rad, as long as the running surface is level..... it strains to ,keep my foot on top of the midsole once things go off camber..... toe box isnt really roomy lke SB2, but not uncomfortable at easy paces. Tounge is rad and doesnt migrate, very thin though, lace bite kicks in on downhills. Zero nonsense in tne heel compartment ... snug, secure, comfy. Midsole/ outsole has a narrower tera firma contact width under ths heel. This narrower contact combined with a single layer stack of foam leads to a skittish ride on trails with lots of undulations on the trail suface. At higher paces, the foam feels high performance soft.... my heel sinks into the midsole, and the heel to toe transition feels fairly clunky, not a smooth seemless neel to toe transition. The bounce is interesting, but the midsole set-up doesnt feel tuned/ dialed. Tread works for mellow dry damp trails, Id keep it mellow. In contrast, the Sb2 handles all levels of technical minus rain and slop. I replaced the laces with 54inch bubble laces. My mens 11 is true to size, my bodyweight is 155 lbs.

Sizing Issue?I see several reviews referring to shoe being too long. That has not been my experience. I am a 10, pretty much across all brands. When running in the 10, my big toes are crunched. So yes, besides my big toes being black and blue after any longer than a 3-4 mile run, this is a great shoe.

If only a bit more width!This shoe felt so light and airy upper too! I bet it is as bouncy as everyone says, I can't say for sure as it was a bit snug and low volume around my toes to really give it a try.plenty of length a thumbs width just like I prefer but too close for comfort for my foot shape unfortunately. Otherwise very light and upper could be softer but certainly seemed breathable. Very nice built shoes wish it had worked for me, just a bit more room please Asics.

Best Non Plated Half/Full Marathon ShoeSeems to achieve it all: still high shock absorption but light and highly responsive. Great for longer races (half/full marathon) when looking for great cushioning without sacrificing energy return

Sweet Spotthese address everything that went wrong with the Superblast 2, with a bit more versatility at different places and much smoother ride. If you are a higher cadence runner (175+ per min) I think you'll enjoy these regardless of foot strike. hopefully the new midsole material will keep the durability high. I only have about 60 miles on my pair, but i'm pleased with how they broke in. fit details: I sized down half a size from my usual. con: reaching for another pair of shoes after running in these.
