Our MERINO+ GREY Socks ensure you maintain your feet always warm and dry even on cold winter rides. We designed a double Merino® yarn complete sock only leaving the instep critical areas with a lighter density for extra freedom of movement and breathability. But still, our Merino socks are thin enough to fit your preferred cycling shoes.

We aimed for a comfortable and warm feel, with a two colors elegant design. You got the option of wearing the socks over your long bibs or under them. Grey and white colors are a perfect match with our long bibs colors and featuring ONCEUPON logos on them.
