    Great socks but not sure if they're too girly with roll up

    Extremely comfortable. Wasn't sure what size to order since I wear a size 13 shoe, so I originally ordered the size for "shoe size 13-15." Wrong choice! The padding on the bottom of the sock would "ride up," so I exchanged them for the next size down and those fit great.

    Great Customer Service. Fast delivery....like 2-3 days! Same price as in the store including the shipping. Many times, the stores don't have exactly what your looking for or they have 1 pair left.... Very happy!
