Adidas launches ADIZERO Prime X Strung running shoes

The weirdly wonderful world of thebest running shoesis forever changing. It feels like yesterday when we all ran half marathons and marathons in racing flats with soles as flat as a pancake. Then, in 2017, Nike released the Vaprofly 4%, featuring the ZoomX cushioning technology, which forever changed competitive running as we know it. The Super Shoe was born.

Fast forward five or so years and Super Shoes areeverywhere. Every self-respecting running shoe manufacturer has their own version, from Adidas to New Balance to Saucony and more. Super Shoes aren’t frowned upon anymore, as the market saturation made them more accessible than before. They are so commonplace that companies started rolling out a new take on the concept: the Super Trainer.

Despite what the name suggests, Super Trainers aren’t just your standard running trainers. In fact, they are often faster and more intimidating-looking than Super Shoes – so why are we calling them trainers? Why are they often ‘banned’ from racing? What are they for? And should you buy them? Let’s find some answers.

What are Super Trainers?

Super Trainers are high-stack running shoes often featuring at least one stiff plate embedded in the midsole. The maximum stack height of these shoes is usually over 40 mm. Some, such asAdidas Adizero Prime X 2 Strung, have multiple carbon plates sandwiched between the different foam layers for more propulsion.

Although they are called trainers, Super Trainers can actually make you run faster than some Super Shoes explicitly designed for racing. That’s because they are further optimised for speed and leg preservation over long distances to a degree that might be classified as mechanical doping.

Why are they banned from racing?

Back in 2019, there were a lot of debates about what, at the time, was probably the most successful road racing shoe, theNike ZoomX Vaporfly NEXT%. The ‘Vaporfly’ ruffled many feathers, so much so that the conversation about running shoes and mechanical doping got into mainstream media, prompting the World Athletics to address the situation.

What they did was to limit the stack height and the number of stiff plates embedded in the midsole in shoes used for racing. And since they didn’t want to undo the records already set in the Vaporfly and similar running shoes, they drew the line there: 40 mm max stack height and one stiff plate.

This applies to all World Athletics road events, including running and race walking, and cross-country events (non-spike shoes). Mountain and Trail Races haven’t got any thickness regulations. What this means is that if you ran a World Athletics race in a ‘banned’ shoe, your time won’t be accepted.

Pros, of course, don’t use non-approved shoes for racing. But should you break the 2-hour world marathon record in theSaucony Kinvara Proor theNew Balance SuperComp Trainer, your time wouldn’t be official.

Should you buy Super Trainers?

Super Trainers aren’t cheap. In fact, they are often the most expensive in companies' lineup. Some Super Shoes, like theSaucony Endorphin Eliteand thenewly announced Adidas Adizero Adios Pro Evo 1, are also costly, but they can be used on races, so one might justify the price, thinking they can be used for any purpose.

However, Super Trainers can only be used for training, or more like non-racing, which limits their versatility. And considering the high asking price, some runners might not be able to justify buying one, which is fair play. Those who like to push their limits and have some disposable income should try Super Trainers, though, as they provide a significantly different running experience.

What are the best Super Trainers right now?

We consider the best Super Trainer the one that pushes the concept of running shoes the furthest without compromising the running experience and performance, which currently is the Adidas Adizero Prime X 2 Strung. These shoes are incredibly comfortable to run in, and thanks to the massive stack height and two carbon plates, they provide oodles of energy return and preserve your legs over long distances.
