Britain’s Jemma Reekie has dismissed speculation that her recent enhancement is linked to her prototype Nike shoes.
Addressing questions about her spikes for the first time, she said her improvement was the result of pushing her body “to the absolute limit”.
Nike shoes and spikes have been in the news for the past few weeks due to new World Athletics rules.
Under the new regulations, athletes will not be able to compete in prototype shoes from April, but currently five-time European champions Laura Muir and Reekie can race in shoes not available in stores.
In preparation for Reekie’s race in Glasgow, questions about his shoes were closed by his reps, but trainer Andy Young has previously said his spikes will comply with the new rules.
Reekie, bringing up the subject for the first time after winning the 1500m at the Glasgow Indoor Grand Prix, said she would “let the experts” tackle the problem.
Asked how she felt about the speculation surrounding her shoes in response to her fast times, she told BBC Sport: “It doesn’t happen overnight and there’s a lot of hard work .
“I’m 21 and a developing athlete and I push myself beyond the absolute limits and I’m just going to let my legs do the talking.”
Reflecting on her recent form, she said: “I attributed it all to Andy’s training and support as well.
“I have a lot of support from British Athletics and Andy, and the two work really well together. Andy puts detail into everything we do and the support for him on and off the track is just learn too.”
Reekie also said “I’m learning a lot” from fellow countryman Scot Muir, who she trains with, adding: “Everything has gone well this year.”
Earlier this month, Reekie broke Muir’s British 800m record in Glasgow, thrusting her into the spotlight.
She followed that performance last weekend in New York when she broke Muir’s British record for the indoor mile and also broke the British record for the 1500m in the same race.
Muir, who was aiming to break the 1000m world record in Glasgow but fell short despite a clear victory, also addressed the debate surrounding Nike shoe technology.
Speaking after her race, she told BBC Sport: “At the end of the day it’s up to World Athletics, they make the rules and regulations about these things, so it’s up to them to decide what happens and in which athletes are allowed to compete.
“As an athlete, all you can do is focus on yourself. We train as hard as we can and we go out there, we have fun and we love the sport.”
Muir also confirmed that the cleats she was wearing will be legal under the new World Athletics rules, saying, “Yes, I believe they will.”
Reekie will race indoors again next week in France, then focus on qualifying for the Tokyo Olympics.
