Negative effects of spiked armor?

[Suppressed Poet]

Krakiipedia talks amout how armor accessories halve padding, but I can't find any information on an entire armor suit that is spiked plus padded.

Say for instance you have HCP spiked full plate. Does the spiked have any negative effects to the armor?

Thanks in advance!

Attacking with, defending from, or both?
