All Women's Road Shoes

  • Daily TrainersDaily Trainers

    The baseline definition of a running shoe. Daily Trainers lean on time-proven designs, technologies and features for dependable cushioning, support and comfort. They're a staple in every runner's closet, and if you are new to running shoes, then you should start your journey here.

  • Performance TrainersPerformance Trainers

    Performance Trainers provide a springy feel and make longer runs easier and faster runs faster. While quicker than Daily Trainers, Performance Trainers are not nearly as fast as Super Shoes. Due to a focus on keeping things light weight, Performance Trainers are less durable than Daily Trainers. These can also be a good option for one's first race shoe.

  • Super ShoesSuper Shoes

    Super Shoes are the fastest running shoes you can buy. They are designed to race your absolute best and represent the pinnacle of running shoe technology and innovation. They have the highest energy return foams and plates for new levels of performance. Low durability, but maximum speed is the name of the game here.

Men'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.

Cushioning Level

  • Cushioning level, or stack height, refers to how much shoe is between your foot and the ground. For this category, we reference the amount of cushioning 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.

  • Barefoot

    0-13mm. The Shoe generally does not have a midsole and feels like there is no cushioning. This shoe is all about feeling the ground underfoot.

  • 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 fall near the middle of the spectrum.The shoes in this category are verstaile 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.

Stability Level

  • Neutral

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

  • Stable

    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.


Product Details:

Engineered for peak performance through the insights of top long distance athletes, the New Balance FuelCell SuperComp LD-X v3 blends cutting-edge innovation with race-proven design. Delivering methodical refinements to its predecessor, this advanced super spike continues to deliver a fast and light racing option with added efficiencies to help you PR on race day.

In order to deliver the lightest weight design possible, the LD-X v3 features 100% PEBA based FuelCell foam that is ultra bouncy and responsive. The soft super foam works together with a full-length carbon fiber plate that is stiff and aggressive enough for all out efforts, while offering just enough comfort and stability to make it through the longest track events. For even more performance on race day, the shoe features a higher toe spring that provides a fast transition as well as a modified spike plate for ultimate traction. The carbon plate continues to be integrated into the midsole but version three offers a little more versatility through a forefoot cutout that delivers a little more flex at a decreased weight. Along with an update to removable pins and a more locked in race day upper, the LD-X v3 offers small but noteworthy changes that will help high level athletes run their best when it matters most!

Whether you're a high level school athlete looking to step up your game, or a professional athlete looking for every edge on race day, the New Balance FuelCell LD-X v3 offers top end performance for any of your distance running needs.

 What You'll Love:

  • 100% PEBA FuelCell foam with higher toe spring for a fast and efficient ride
  • Addition of removable pins (from fixed pin layout) for more customization of spike length
  • Race fit upper for comfort and performance

How We Measure Our Shoe Specs

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

  • Weight

    The weight is based on a Men's size 9 for Men's and Unisex shoes or Women's size 8 for Women's shoes. The weight listed is for a single shoe, including the laces.

  • 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.

  • Fit (width) options are Narrow - Snug - Average - Roomy - Wide.

  • Sizing (length) options are Short - True - Long. 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.
