Rigid plates beneath the forefoot and thick, plush soles reduce energy loss while running, but there is little quantifiable data on how the shoes impact performance. The shoe's purported boost comes from its construction.

It is the fastest time in the women's event since American Florence Griffith-Joyner’s 10.62 in 1988.
Shelly-Ann Fraser-Pryce of Jamaica realized a dream Saturday by clocking 10.63 seconds over 100 metres at a meet in Kingston. Bolt, who retired from competition in 2017, made his feelings about the technology known this month, calling the shoes "weird and unfair." Super spikes, which are now available from a variety of the biggest sports brands - including Puma - are facing criticism for their perceived increases to a sprinters' speed. "If we compare it, for instance, to their times last year, we can't their gains all to the shoe because there's lots of other factors to why they might get faster." The athletes are obviously incredibly talented and they've been training really hard," said Healey, who is also manager of footwear innovation for Puma. "The shoe, we are seeing, does contribute to these improved performances, but there are lots of other things. In June, Jamaican Olympic gold medallist Shelly-Ann Fraser-Pryce ran the fastest 100-metre in 33 years wearing a pair of Nike Air Zoom Maxfly shoes.īut footwear biomechanist Laura Healey, who has studied gains in athletes who compete with the shoes, says there's more to the recent broken records than just the footwear. A record held for more than a decade by Usain Bolt could be beat at the Tokyo Olympics thanks, at least in part, to shoes.Īthletes wearing so-called super spikes, a new family of shoes worn by sprinters, have slashed records in recent months.
