One foot for each testicle

[marathonman]

This is an unusual request. Thanks for considering the translation.

I practice Israeli martial arts called Krav Maga. We create slogans on t shirts and sweatshirts twice per year. Part of Krav Maga is defending yourself from attackers by kicking them in their soft spots. My instructor is a very nice person and very smart but doesn’t know Latin. She asked me if I could help her with that phrase. One foot for each ball (testicle).

i thought it would be :

Pes unus testis unus.

I appreciate your help!
