Adidas adizero synthetic wearers?

Hey i bought the adizeros in leather last time and they were really nice but they leather wore down pretty fast. I was thinking about getting the adizero ii synthetic this time but last time i tried on the first ones in synthetic they looked really weird when i bent my foot to move. I wear a size 7.5/7 in adizeros so they are kinds small but i was worried the syntheitc might crack cause it looked like it was going to when i tried them on. So wondering if there are any adizero wearers same size as me or anyone got a nice review about the synthic or should i wait for the new predator adipowers
