hi! i saw you asked about nike free runs, what exactly would you be using them for? if you just want them to wear and walk around in then they are perfectly fine and comfortable but if you are going to use them to do a lot of running i would not recommend them just because they don't have much support so you feet/ankles/knees may start to hurt. i bought them for running when i was doing 2-3 mile runs and i didn't like them
