Amazing socks......
Size: Large, Color: (100) White / White / Black
They are Great...... Great price compared to store prices, not to thick or thin, they stay up where they belong- no sliding down under the heel, they wash up amazingly, cushion and comfort, no shrinkage, moisture wicking, feel so good on........
