Shyu's performance training sock uses technology from their fantastic race socks and packages it into a product more suitable for everyday use. Version 2 updates the fabrication with an organic nylon blend that further increases softness and durability. 

Coming in a convenient three pack, they're lightweight and breathable, just like the race day version but there's more cushioning and support to make the training sessions easier. They've also updated the logo to be reflective—aiding in those dim lit training sessions.
