New chapter of the prohibited shoes lawsuit: after the World Athletics decision by change rule 143 of its technical regulation defining the very precise measurements allowed to the manufacturers, the consequences arrive, destined to make much more talk in the environment.
Nike, the company that most of all was at the center of the controversy with its Vaporfly and the Alphafly Next, presented a new series of footwear, all rigorously with the “heel”, just like the mythical ones used by Kipchoge and the others: a thickness of 39.5 mm, with an internal carbon blade, absolutely allowed by the norm 143. The new shoes thus guarantee the now famous technical advantage in terms of amortization, quantified by experts in about 3% of the time.
The way to Tokyo it is so traced, with the highly anticipated Viperfly for sprinters, always with the heel: however, only the centometrists will be able to use it, because it is the same US company that admits possible difficulties in cornering grip for the wearer. It is difficult to target Usain Bolt’s 9 ″ 59 which has endured since 2009, although Coleman’s 9 ″ 76 in Doha bodes well for a performance that is at least close to the historical miracles of the Jamaican.
