SOCKGUY socks are available in two sizes, S-M and L-XL.

 

My barefoot is 26cm and I take shoes in US 9.5.

S-M is a little bit tight for me, so I always go L-XL.
But, I own both of them and they fit nicely with its great stretch.

I’d like to recommend them for riding a bike of course, your daily life and room socks in the winter.

 

There’re Standard, Long Socks, Wool, and SGX6 which is a bit pricy one.

“SGX6, the model made for the higher performance.”

It’s not so easy to understand when I read the description, but they obviously feel better.

All of the streamlined sole, seamless toe and zero-slip arch support will provide you with exceptional comfort.

 

FYI, you should turn them inside-out to wash and dry them on low heat.
