We recently sat down with Spencer Nel, Senior Director of Sports Marketing at Adidas, to dive deep into the fascinating world of Illegal running shoes.
From regulations to innovations, here’s everything you need to know about the limitations and potential of building the fastest running shoes.
Illegal Running Shoes
First, what are illegal running shoes?
Illegal running shoes are the rebels of the running world, breaking all the rules set by World Athletics. Think of them as the shoes that push the boundaries a bit too far. These shoes don’t play by the book when it comes to stack height—the thickness of the midsole that gives you that cushy feel.
For road running, you’re looking at a max of 40mm with just one carbon plate allowed. On the track, it’s currently a slimmer 20mm, though that’s about to get standardized across the board.

This change aims to simplify the gear requirements for athletes, ensuring they don’t need multiple pairs of spikes for different events.
But why the fuss? Well, higher stack heights and multiple carbon plates can give you an unfair advantage by providing extra bounce and energy return, making you feel like you’re flying rather than running.
These supercharged shoes can also reduce fatigue, meaning faster recovery and more intense training sessions.
Amanal Petros, after setting a German record in the Berlin Marathon, shared a remarkable insight into the benefits of advanced running shoe technology. He said, “The day after the marathon, I went for a 10K shakeout run, but I felt like I’d run a half marathon the day before instead of a full marathon.”
This statement speaks volumes about the recovery advantages provided by modern running shoes. The enhanced cushioning and energy return from the latest super foams means that even after pushing his body to the limit in a marathon, Petros felt significantly less fatigue than expected. This reduced wear and tear on his muscles allowed him to bounce back quicker, maintaining a higher level of performance without the usual post-marathon exhaustion.

Who Has to Follow the World Athletics Rules?
If you’re an elite athlete invited to major events, these rule-breaking shoes are a big no-no. They could get you disqualified faster than you can say “personal best.” For elite competitors, the stakes are high, and every little advantage counts, which is why the rules are so strict.
They need to ensure a level playing field where the winner is determined by skill and endurance, not by who has the bounciest shoes.
For the average runner, the rules are a bit more relaxed. You won’t be stopped at the finish line to check your shoe specs. This leeway means general runners can often wear shoes with higher stack heights that elite runners can’t use.
So, while the pros are meticulously measured and monitored, the rest of us can enjoy a bit more freedom with our footwear choices.
The Role of Super Foams and Carbon Plates
Adidas’ Rod Technology
Adidas has truly stepped up their game with their innovative Rod carbon plate technology. Unlike traditional solid carbon plates, which can feel a bit like strapping a rigid board to your foot, Adidas’ Rod structure is designed to mimic the natural flexibility of the foot. Imagine a setup that bends and moves with you, providing less restriction and a lot more comfort.
So, why is this a big deal? Well, for starters, the Rod design helps with weight reduction. Less weight means less energy expenditure, which can make a significant difference over long distances.
But the magic doesn’t stop there. This design also enhances performance by allowing a more natural stride.
Think about it: when your shoe moves naturally with your foot, every step feels more fluid and efficient. You’re not fighting against the shoe, but rather, it’s working with you. This means you can maintain a better running form, reduce the risk of injury, and potentially run faster and longer.
Adidas’ approach with the Rod technology is all about finding that sweet spot between innovation and practicality.
They’ve managed to create a shoe that stays within the rules but pushes the boundaries of what’s possible in terms of performance and comfort.
Shoe Checks at Races
Imagine trying to check the shoes of 30,000 runners at a marathon like Boston—it’s simply not practical!
Instead, the focus is on elite athletes. These are the runners who are setting records, winning prizes, and representing the sport at the highest levels. For them, compliance with World Athletics regulations is non-negotiable.
Why such strict scrutiny for elites? Because their performances can set benchmarks, influence the sport, and even sway market trends.
For the rest of us mere mortals, there’s a lot more flexibility. Recreational runners aren’t subjected to the same rigorous checks.
This leeway allows everyday runners to benefit from advanced shoe technology that might not be allowed in elite competitions.
This balance helps maintain the integrity of the sport at the top levels while allowing the broader running community to enjoy the advancements in shoe technology.
Future of Running Shoe Regulations
The future of running shoe regulations is shaping up to be quite an exciting journey. Spencer Nel pointed out a crucial need for clearer measurement guidelines.
Currently, some shoes on the market appear to have higher stack heights in specific areas, giving runners potential advantages that may not be entirely within the spirit of the rules.
To address these ambiguities, an open dialogue between manufacturers and regulatory bodies is essential.
Future clearer guidelines will ensure that all athletes compete on an equal playing field, while still allowing for innovation in shoe technology.
This means more precise definitions of where and how stack height measurements are taken, ensuring no sneaky additions in less regulated parts of the shoe.
Adidas’ Versatile Offerings
Adidas has truly embraced the diverse needs of runners, offering a versatile range of products designed to cater to different aspects of training and competition.
The EVO 1 is a marvel of modern running shoe technology, tailored for elite races. With its cutting-edge design and advanced materials, it’s built for speed and performance. This shoe meets all the stringent regulations, making it a legal choice for top-tier competitions while still providing the maximum advantage allowed.
When Assefa Tigist shattered records at the Berlin Marathon wearing the Adidas Pro Evo 1, the world took notice.
The performance boost provided by the Pro Evo 1 created a fervor among the running community, with people eager to experience the same benefits that propelled Tigist to victory.
In fact, Adidas found themselves in a situation they hadn’t anticipated—they simply couldn’t keep up with the sales.
On the other hand, the Prime X is a fantastic choice for training and everyday running. Featuring a higher stack height, it offers extra cushioning and support, making those long training sessions more comfortable and less taxing on your legs. This shoe is perfect for runners who want to enjoy the benefits of advanced technology during their workouts without worrying about race day regulations.
One of the best strategies to optimize your performance is to mix up your shoe choices. Think of it as having a specialized tool for every job. For your training runs, you might opt for the Supernova Rise, which offers excellent support and durability, perfect for clocking up those training miles. Then, come race day, you switch to the Pro 3 or the EVO 1, giving you that competitive edge when it matters most.
Different shoes provide varying levels of support, cushioning, and responsiveness, which can help in balancing the stress placed on your muscles and joints. It’s like having a well-rounded arsenal of gear that prepares you for any running scenario.
A lot of running shoe manufacturers continue to push the boundaries of what’s possible in running shoe technology.
By offering a range of products tailored to different needs and preferences, they ensure that every runner can find the perfect fit for their goals. Whether you’re aiming for a new personal best in your next race or just enjoying the journey of running, there’s a shoe for you.
