When Jemma Reekie turned the quickest British girl to run 800m indoors, she was as shocked because the spectators cheering her on in Glasgow.

After stopping the clock at 1 minute, 57.91 seconds, slicing 4 seconds off her private greatest, the 21-year-old Scot tweeted: “I don’t even know what occurred on the market. I must attempt to course of this.”

Her expertise, indomitable work ethic and urge for food for coaching have been all hailed after the beautiful race however one query mirrored a debate raging throughout the athletics world for the previous 5 years –what did she have on her toes?

Ever for the reason that Nike Zoom Vaporfly 4% prototype was worn by every medallist within the Males’s 2016 Rio Olympic Marathon – Kenyan runner, Eliud Kipchoge, received the race in 2 hours, 8 minutes and 44 seconds – the evolution of a brand new breed of “tremendous shoe” has remodeled athletics, leaving a path of damaged world data and controversy.

Some see the problem as an thrilling and inevitable evolution, whereas others examine the battle to create the world’s simplest working shoe to an arms race.

“It’s completely modified the panorama of efficiency previously 5 years, and is the largest tools change for the reason that introduction of artificial tracks,” stated Norrie Hay, excessive efficiency athletics coach at Glasgow Faculty of Sport.

“A lot of the main data have been damaged within the final 5 years, so it’s giving athletes a bonus however we will’t say it’s unfair as a result of these footwear are at present authorized. For shoe producers, it’s like an area race to get the perfect shoe to your athlete, in order that they get that 1 or 2% enchancment to win an Olympic gold, which then turns into advertising and marketing gold.”

Nike’s Air Zoom Alphafly Subsequent% working shoe.

Beginning with highway racing in 2016 then monitor occasions in 2019, athletes carrying cutting-edge footwear have seen their instances and efficiency degree improve.

Nike formally launched its Vaporfly shoe in 2017, claiming it made highway runners 4% extra environment friendly through the use of a mixture of a super-charged, super-soft foam sole and a full-length carbon plate. This elevated working economic system meant athletes used much less power, serving to them run sooner for longer, particularly within the final tiring minutes of a marathon. It has proved revolutionary.

After continued improvements, Nike loved presumably the biggest-ever advertising and marketing occasion for a working shoe in October 2019, when Kipchoge turned the primary runner to interrupt the two-hour marathon barrier in 1 hour 59 minutes and 40 seconds. He wore Nike Air Zoom Alphafly NEXT% footwear, a bespoke model of the Vaporfly.

In the identical weekend, Brigid Kosgei additionally smashed Paula Radcliffe’s 16-year-old ladies’s marathon file by 1.21 seconds, once more in Vaporflys. Radcliffe stated on the time: “It’s simply innovation. Identical as my footwear have been higher than my predecessors’.”

Nike’s prototype spikes have had an analogous performance-enhancing impact. The Nike ZoomX Dragonfly spikes, billed because the “quickest footwear ever”, have been worn by each runners who broke the lads’s 10,000m and the ladies’s 5,000m data in October.

Manufacturers like Adidas, New Stability, Reebok, Hoka and Asics have since launched their very own tremendous footwear to rival Nike, going some option to levelling the taking part in discipline. Whereas these footwear, and extra superior prototypes, are free to elite athletes through sponsorship offers, they value round £250 for members of the general public to purchase.

It’s clear to specialists and coaches that advances in working shoe know-how helps athletes push the boundaries of racing efficiency. Mark Pollard, head of efficiency at Scottish Athletics, stated: “The evolution of know-how has impacted most sports activities. Fina, the governing physique of swimming, banned new low-drag swimming fits in 2009 as a result of so many world data have been decimated inside such a brief house of time.

“Whether or not these footwear change into accepted as the brand new regular or if there’s a major assessment, and it goes down the road of the banned swimsuits, will probably be attention-grabbing to see however the feeling is that these footwear are right here to remain.

“Innovation has all the time been a part of the evolution of athletics. Working surfaces, spikes and clothes have all the time progressed and developed to assist folks run sooner.”

Persevering with advances in working shoe know-how initially left the game’s governing our bodies scrambling to implement guidelines to make sure everyone seems to be competing on an excellent taking part in discipline. In April 2020, World Athletics (WA) determined that each one footwear worn in competitors should be freely out there “on the open retail marketplace for 4 months”. Soles could possibly be no thicker than 40mm and soles with spikes no thicker than 30mm, with different situations various from self-discipline to self-discipline.

Final August, World Athletics issued a listing of authorised footwear. In December, it introduced prototypes could possibly be utilized in WA-sanctioned competitions, however not the upcoming Olympics, and will solely be worn for 12 months earlier than being made out there to the general public.

Former Scottish gold-medal relay runner and Olympian Brian Whittle sees this technological leap as inevitable however one which requires strict regulation. “You’ll be able to’t blame a shoe producer for making a product that’s too good, or an athlete for carrying them,” he stated. “It’s as much as the powers that be to create the principles that permit for a degree taking part in discipline.”

World Athletics president Sebastian Coe, whose 38-year-old British males’s indoor 800m file fell to Elliot Giles in February, has shrugged off considerations about new footwear and monitor spikes, stating he doesn’t need to “suffocate innovation”.

NIKE – viperlfy spikes

He stated: “I don’t assume we’ve reached that time the place world data are being handed out like confetti. This stuff are available in cycles. There’s a built-in dynamic the place shoe firms make investments some huge cash into the analysis and improvement of footwear.”

In her record-obliterating run in Glasgow, Reekie and her coaching associate, fellow Scot and 1,500m European champion Laura Muir, wore prototype Nike spikes. The footwear have been consistent with World Athletics pointers and would quickly be in the stores in retailers, legitimising her phenomenal efficiency.

“When Jemma broke data in Glasgow, she was requested about her footwear however you need to keep in mind that she’s coaching with Laura Muir,” famous Paul Freary, efficiency product editor at trade publication Athletics Weekly. “She basically has the perfect coaching associate on the planet, plus the perfect science, amenities, teaching and vitamin behind her. These components develop on a regular basis, so that you’re all the time going to see performances improve by sure margins.”

Innovation apart, some concern fast advances in shoe know-how might injury the game’s repute and be unfair to athletes. In an interview with Athletics Illustrated final yr, Liz McColgan, one among Scotland’s all-time nice distance runners and coach to daughter Eilish McColgan, stated: “The time has come to cap technological enter. Athletes needs to be on the beginning line as equals and presently they don’t seem to be.”

Others are extra vital. Eurosport athletics commentator and former British bronze medal-winning center distance runner, Tim Hutchings, stated: “Successfully, these footwear are virtually a legalised type of doping as a result of the know-how is enabling folks to carry out approach past what they’d do naturally. Sadly, there’s a parallel with steroids in that these footwear supply larger safety and assist athletes recuperate faster and subsequently practice more durable.

“We hear some folks reply to this know-how higher than others, so the footwear are creating winners and losers earlier than the beginning gun goes off.”

Final month, Nike stoked the controversy by failing to launch its newest tremendous shoe, the Viperfly, designed particularly for 100m sprinters, final summer time as scheduled. Some imagine it might reappear earlier than the Tokyo Olympics. Might data like Usain Bolt’s iconic 9.58 second 100m be below risk to an athlete sporting Viperflys?

Norrie Hay, who has coached athletics for 17 years, says the margins are minute: “It could possibly be two years earlier than Usain Bolt’s file falls to somebody with a lesser capacity than Bolt however with a shoe that provides them a 4% benefit. In terms of the 100m dash, the margins are so small that any slight benefit can imply the distinction between coming first and final.

“I don’t see any scenario the place these footwear will probably be banned. World Athletics might need to tighten the rules, however these tremendous footwear are right here to remain.”

5 years on, specialists, coaches, governing our bodies and commentators stay undecided on the problem however agree that any advances can not undermine the game or opponents.

As Mark Pollard says: “Athletes would really feel deprived in the event that they weren’t carrying these footwear however what you’ll be able to’t do is diminish their achievements. It’s not like they’re sitting on the sofa after which pop on these tremendous footwear to run a world file. It could be a disservice to immediately’s athletes if we solely targeting these footwear reasonably than all of the laborious work and dedication they put in.

“Equally, you’ll want to respect these previously who’ve produced distinctive performances in what could possibly be seen as weaker know-how. World Athletics must preserve tightening and refining the principles round trainers as they evolve and knowledge evaluation continues.”


How tremendous footwear work 

Paul Freary, efficiency product editor at high trade publication Athletics Weekly, explains the science behind the tremendous shoe: “A carbon fibre plate is embedded within the foam cushioning of the shoe, and that foam is far lighter and springier.

It’s like a rubber ball that rebounds its power a lot faster on the bounce. The carbon plate stabilises that materials, so that you get a larger power return. It additionally stiffens up the forefoot, which creates an even bigger lever that can assist you push off more durable and sooner.”

Their capacity to reinforce restoration additionally provides athletes long-term advantages, he added.

“There’s no rule to what footwear you’ll be able to practice in and, as these supplies are so superior and springy, your legs don’t really feel as drained on the finish of a race and restoration is faster.”
