Hmm, weightlifting shoes…maybe that’s why a lot of people on this forum claim to run well under 4.00 for 30m yet run 12.00 in the 100.
Weightlifting shoes are great for quad development but poor for people who are aiming at posterior chain work. Even the deepest squat in WL shoes doesn’t hit the backside as well as a decent squat in chuck taylors. Going along with that, I would almost guarantee you 99% of the top 100/200m guys aren’t using WL shoes.
