google around. i searched best shoes for point guard and one of the shoes that i found got mentioned a lot was cp3's. sites spoke about what the strengths of particular shoes were. cp3s were spoken about their traction and hold on your foot which i liked the sound of. i went and tried some out and they were awesome. they suit me as i love to change direction and really push hard off my foot when i drive.
i think you should think about what qualities you want and how much you want to spend. then google google google. go into a store and try on 2 , 3 pairs of shoes. i really liked what i heard about kobe system 8's but they never had any in my size to try out :( . i tried on hyperdunks and cp3's and went with cp3's. love them. be prepared to spend $160+ for really good shoes though. that being said spending more on shoes doesn't make you a better player. it just makes it a lil bit more enjoyable , safer , and maybe the tiniest fraction easier to play the way you want to.
happy hunting
