I usually like it tight
Cloud White / Dash Grey / Lime Burst
The wrap around my foot is so incredibly tight, I don't even need to lace them up. It is like the tightest glove you can imagine. I don't have thick socks on, and I don't lace them up. And still these fit so tight you can barely get your foot into the shoe. The length is good, the width is good, but it is the sock mesh they are using is not designed to give any extra room in there.
