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.

Super ShoesSuper 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.

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.
-
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 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.
At A Glance:
- First shoe to enable a pro to break 6 hours in the 100K
- Stratospheric stack of unreal superfoam
- Maximum velocity for road races well beyond marathon distance
Product Highlights:
Crafted to shatter the fastest 100K time ever run (which it did, and then some), this concept road racing shoe is now available to the public. Whether you're a top performer looking to set your own records for road ultramarathons and standard marathons, or you just want to own a bleeding-edge piece of history, this is it.
For the midsole, the tallest-ever stack of uncompressed Lightstrike Pro Evo superfoam provides boundless energy return. This formulation is a stunning 35% lower density than the version used in the shoe's Adios Pro Evo sibling, for a soft and impossibly ultralight ride. For inherent stability, this foam provides high sidewalls around your heel for a deep bucket-seat ride.
The Prime X Evo also debuts an all-new Energy Rim stiffening element, the latest evolution of adidas' championship-proven Energy Rods. Altogether, paired with a dramatically aggressive toe rocker, you get every possible efficiency advantage, making it feel easier to hold your fastest paces for longer.
Its featherweight mesh upper employs a new pattern to create a barely-there feel that disappears on foot, while still offering targeted support for racing. Crucially, the outsole promises greatly improved traction over the Adios Pro Evo. With full-length coverage of sticky Lighttraxion, plus Continental rubber in the forefoot, you'll feel more confident on slick road surfaces.
Ready to experience the pinnacle of road racing prototypes? Take a lightspeed ride on the adidas adizero Prime X Evo... and don't forget to clear some space on that trophy shelf.

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. 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.

Technologies
MIDSOLE
- Lightstrike Pro Evo superfoam is the lightest uncompressed TPEE that adidas has produced. It's 35% less dense than the Adios Pro Evo version for maximum deformation and energy return at an incredibly low weight.
- Aggressive forefoot rocker acts as a fulcrum situated at 60% of the overall shoe length, mirroring the Adios Pro Evo for maximum forward-rolling efficiency.
- Energy Rim is a next-generation stiffening element, evolved from Energy Rods. It forms a horseshoe-style perimeter to preserve underfoot softness with custom-tuned propulsion.
OUTSOLE
- Lighttraxion GCPU compound is full-length cast polyurethane, offering strong grip and flexible durability at a reduced weight.
- Continental™ rubber is a staple in adidas performance shoes to provide extra traction in the forefoot for variable road conditions.
UPPER
- Ultralight engineered mesh secures your foot with breathable material and the minimum support for powerful racing.
