STYLETHREAD -- LET'S TALK SHOP!

HI, I recently bought the red ones and I cannot fit my feet into them. I am normally a 6 and sometimes a 5.5. I bought the Lalos in a 6 and they are too small. I was curious if anyone else who owns them had this same problem and then with a couple of wears they stretched out? I read the reviews on  Zappos and several said to size down. Should I return them and size up or keep them and they'll stretch out. They are so incredibly uncomfortable right now. TIA!
