Giro socks

[cyan]

Do they (not thick/merino models) run small or large? I'm US 9.5-10, sort of in-between size, and wonder if I should go for M or L in them. I do wear US 9.5/EU 43 Giro shoes, and there is some small space in the toe area. I wear size II in Assos socks (which runs small), and M in De Marchi socks (which runs large).

Any Giro users out there care to chime in?

i have 2 pair. Both fit true to size. The newest 6" ones are plush.

I have two pairs. They are just a little tight.

Edit: they are both Merino, so might not be relevant
