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.

Product Highlights:
Alongside near-twins like the RX:CCD and RX:PNW, the Speedland RX:BLK is a dark-mode colorway with an ultra-durable ripstop mesh upper, distinguishing it from the open spacer mesh of other RX models.
For this RX:BLK's midsole, Speedland proudly continues its use of uncompressed HTPU superfoam for the carrier layer. Together with the drop-in core layer of supercritical foam, you'll experience the best of all worlds: elite and enduring responsiveness with plusher comfort closer to your soles.
This proprietary internal core is removable, to add an optional rigid carbon fiber plate (sold separately) or the flexible Carbitex plate (sold separately) if you wish. With this signature design, you can change your super shoe from aggressive racer to softer trainer and back again.
Up top, its strong ripstop mesh upper is upgraded with a multi-directional Li2 dial. This BOA Fit System dial enables quick micro-adjustments tighter and looser. This means you can literally dial in the PerformFit Wrap to your "just right" setting for secure comfort. Last but not least, the scratch rubber outsole lets you grip and rip long miles at hot paces.

Stack Height
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.
-
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.

Technologies
MIDSOLE
- Uncompressed HTPU superfoam is supercritical aliphatic TPU that isn't compression-molded, but is simply cut and smoothed into shape as the carrier base layer. With roughly 15% more energy return than their other premium foam, it delivers Speedland's highest responsiveness ever.
- Proprietary drop-in core foam is a supercritical blend of OBC, EVA, and nylon compounds for a slightly plusher but still responsive underfoot experience. This thick layer (15 mm heel / 10 mm forefoot) is removable to insert an optional rigid carbon fiber plate (sold separately) or flexible Carbitex GearFlex carbon fiber plate (sold separately). This shoe isn't compatible with custom or third-party orthotics, insoles, or inserts.
OUTSOLE
- Scratch rubber provides generous full-length coverage for confident grip over variable road conditions.
UPPER
- Ripstop mesh is tightly woven, incorporating strategic high-tenacity fibers for durability, protection, and foot lockdown.
- PerformFit Wrap combines three supportive overlays to securely wrap all vital areas of your foot.
- BOA Fit System utilizes a multi-directional Li2 dial to engage the PerformFit Wrap. This dial offers micro-adjustability in both directions, allowing you to instantly tighten or loosen the fit as quickly and as often as you like.
