Also, how thick are your socks? I am extremely sensitive to the tightness of my shoes and socks. I leave my shoes barely fastened, even though I have plenty of room, wide toe box, etc. and I mostly wear very thin wool socks for cycling. I miss my cool looking other cycling socks, but the difference is astounding. Also, I just can't use spd pedals. They cause immediate tingling. I put up with it a bit if I go to spin class, but that's it.
