This is more what I remember training flats (as opposed to "spikes") to be like. Asics Tigers.
When Nikes came on the scene, we went apesh*t over the first pair we saw. They were sooooo different with those wedged heels. My asst coach had the first pair I ever saw, and he called them "nyks". So we all called them that for quite a while. I'm pretty sure the wedge heel on my first pair of Nikes was lower than the Mizuno and PI heels. It was maybe double the thickness of the Tiger.
