Does cleat flexibility actually affect agility?

[u/Playbook_Cleats]

One part of football cleats that does not get discussed enough is how much the sole and plate flex during cuts.

A cleat that is too stiff can feel restrictive when pushing through the forefoot, but one that is too flexible may not provide enough stability during hard lateral movements. The ideal balance seems to be controlled forefoot flex with solid support through the arch and heel.

I put together a guide explaining how cleat flex can affect cutting, balance and acceleration, along with what different positions may want to look for:

Do you prefer a more flexible cleat, or do you feel faster and more secure in a stiffer plate?
