    My new favorite bike sock

    Like the fit of these socks, I wear size 11 shoes and bought the 2XL after reading previous comments. They are not too bulky which results in comfort for riding in warm weather. You can feel the midfoot support and they are labeled for Left or Right foot. Would have been a 4 star for value but I got them on sale on BTD. Liked them so much I bought all 3 colors and the taller version too.

    Great sock for summer!

    I bought several pairs and while they are very well made, they are super tight. I struggle getting them on and straight ie. so the heel portion is lined up correctly. For me they are fairly hard to get off after a long hot summer ride in Walla Walla. If you buy these, order one or two sizes larger at least!
