Two small peaks at heel strike?

[Juan Dura]

Dear biomechanics,

In same cases, we have observed two small peaks at heel strike in the
vertical force (measured with forceplatform). This two peaks appears
with normal people in normal gait.
I have done a literature review, and only one small peak is referenced.

Someone has observed two small peaks at heel strike?
Do you know any reference where two small peaks appear at heel strike?

Thanks in advance
