Etnies Fakie

I just bought a pair of sliding modules Etnies (Fakie), the other day, and when I wore, everything seemed fine. After wearing it for a day at school or they have become a little loose towards the rear. Slip-ons are supposed to feel free on foot or are they supposed to carry on as normal shoes like converse after you tie the laces? I heard there are different ways to wear them, but I do not know how it is supposed to feel. My feet are pretty small, so I bought 7.5 because I know the size 7 is too small for my toes. Any comments? Suggestions?

THEY'RE FAKE. Etnies are very cheap! I vans and modules Sperry slip and they are not free when you wear them with socks
