Yes, clearly. But kicking is not like using claws. You can strike in any direction while kicking, when claws have to be used in one direction only.
Also, if you have boots...
In my opinion, it's not intended to be used for feet.
Tengu have Talons. Normally bird talons are feet. But Tengu art is all over the place. The official rules description puts talons on both hands and feet. So for Tengu it is clear.
Claws are mentioned only on hands for Catfolk, but its hardly perscriptive. Lizardfolk say nothing
